Memory Beta, non-canon Star Trek Wiki

Imzadi is a Star Trek: TNG novel by Peter David.


It began with Spock's World, the first Star Trek hardcover and an eight-week national bestseller. Next came The Lost Years, Prime Directive, Probe and then Reunion, the first Star Trek: the Next Generation hardcover -- all of them major New York Times bestsellers. Now, Pocket Books, proudly presents the second Star Trek: The Next Generation hardcover: Imzadi, the long awaited novel that takes the crew of the U.S.S. Enterprise from the outer limits of time to the inner reaches of the human heart.
Years before they served together on board the U.S.S. Enterprise, Commander William Riker and ship's counselor Deanna Troi had a tempestuous love affair on her home planet of Betazed. Now, their passions have cooled, and they serve together as friends. Yet the memories of that time linger and Riker and Troi remain Imzadi - a powerful Betazoid term that describes the enduring bond they still share.
During delicate negotiations with an aggressive race called the Sindareen, Deanna Troi mysteriously falls ill... and dies. But her death is only the beginning of the adventure for Commander Riker -- an adventure that will take him across time, pit him against one of his closest friends, and force him to choose between Starfleet's strictest rule and the one he calls Imzadi.


The End[]

Chapter One

Commodore Data, commander of the USS Enterprise-F, is on the Forever World to visit the Guardian of Forever. He views Captain James T. Kirk along with his crew leaving Forever World after Kirk allowed Edith Keeler to die in the past in order to prevent altering history.

Data wishes to touch and speak with the Guardian and so obtains the necessary permission from Mary Mac, an Orion scientist employed on Forever World.

Chapter Two

Admiral William T. Riker, commander of Starbase 86, receives a visit from his second-in-command, Lieutenant Dexter. Dexter informs him that the surveying ship Chance will be stopping at the base next week, that Starfleet is complaining that the base is not processing its 1021-JKQ forms rapidly enough, and that Riker has a personal communique from Betazed. Lwaxana Troi is dying and wishes to see Riker. Starfleet Command has sent the Hood, commanded by Captain Wesley Crusher to transport Riker to Betazed.

Chapter Three

Data and the Enterprise Science Officer Lieutenant Blair share a meal with the six scientists posted on Forever World. Answering a question of Data's, Mary Mac notes that Mar Loc has not been seen in a few days. Mary Mac and her assistant Harry relate a story of how research done at Forever World has recently led to the end of centuries of warfare between two planets: Gamma Delta and Gamma Origii. Mary Mac then tells Data she has something very interesting to show him. It is later revealed that she has learned that the death of Counselor Deanna Troi at the Sindareen peace conference was a 'focal point' in the timeline.

Chapter Four

Wesley Crusher, now Captain of the Hood, discusses the past with Riker.

Chapter Five

Upon arriving at Betazed, Riker and Crusher beam down and encounter Wendy Roper, now Wendy Berq, who mentions that her father, (Mark Roper) died about ten years earlier. Riker, Crusher, and Wendy, enter the Troi home and are greeted by Mr. Homn. The home is filled with furniture and memorabilia, although Lwaxana's bedroom is completely empty except for the bed which she is in. Riker apologizes to her, but just as she is dying, Lwaxana grabs him by the throat telling Riker that Deanna's death was his fault and that he should have saved her.

Chapter Six

Riker attends Lwaxana's funeral as she is entombed in the Troi mausoleum next to her daughter, Deanna. Crusher and the Hood prepare to leave as Riker reveals that he will be staying on Betazed as Lwaxana's will dictated that he is to go through her memorabilia and catalog it. Crusher asks how Deanna dies and Riker prepares to tell him the whole story.

The End of the Beginning[]

Chapter Seven

Captain Picard summons Commander Riker to his ready room to discuss the upcoming Sindareen peace talks. The Sindareen have achieved several Pyrrhic victories over the Cordians, the Byfrexians, and the Luss, but have destroyed their own economy in the process and so now are suing for peace. Riker notes that Counselor Troi has had some experience with the Sindareen before, but won't go into further detail.


Deanna Troi.

Chapter Eight

Riker goes to Troi's quarters only to find that she was in bed with Dann Lendann, an old friend. Riker goes to Ten-Forward and discusses the situation with Guinan. Troi enters, angry with Riker for the way he acted, and Riker apologizes to her and they make up.

Chapter Nine

The peace conference begins aboard the Enterprise now in orbit over Sindar. Troi notes that Sindareens can be difficult to emotionally read, but she believes that they genuinely want peace. Eza, an aide to Nici, the Sindareen ambassador is not enthusiastic about the proceedings. Dann sits next to Troi and leaves with his arm around her waist.

Chapter Ten

Riker wakes up in his quarters as Troi screams "Imzadi" in his mind. He calls for Dr. Crusher to meet him in Troi's quarters and he races there only to find she is in convulsions, a confused Dann standing beside her. Dr. Crusher and Dr. Selar arrive shortly after, but Troi dies a few moments later.


Riker finishes telling his story to Captain Wesley Crusher. Crusher leaves and Riker goes to the Troi house to begin going through Lwaxana's possessions. He finds that Deanna has kept several items that remind Riker of his early relationship with her including a poem that he wrote for her. He finally breaks down and begins to cry.

The Beginning[]

Chapter Eleven

Lieutenant William Riker prepares to leave the USS Fortuna when Captain Lansing and his crew throw him a surprise going away party. Kathy Li, who had a relationship with Riker, has baked him a cupcake - her nickname for him. Riker has been promoted to first officer of the USS Hood, but the Hood was damaged in an attack by Sindareen Raiders and so will be undergoing repairs in dry dock for two to three months. During that time, Riker will be stationed at the Federation Embassy on Betazed.

Chapter Eighteen

Chapter Nineteen

Troi takes Riker to the Betazed museum of art. He has difficultly appreciating any of the artwork. Troi takes Riker outside to a tree and challenges him to hang from a branch longer than she can.

Chapter Twenty-Eight

Riker arrives at the Troi home, and although Lwaxana is forced to thank him for saving Deanna's life, she is furious that he "took advantage of her." Lwaxana demands that he leave and when Deanna appears, she agrees, telling Riker that it was a mistake to get involved.

Chapter Twenty-Nine

The Middle[]

Chapter Thirty-Four

Riker donates Lwaxana's effects to the Betazed museum as the Enterprise arrives to transport him back to Starbase 86. Data informs him that he has learned that Deanna's death is a 'focal point' in time and that she lives in an alternate timeline. In that timeline, she detected the Sindareen were lying at the peace conference and the Federation refused to sign the peace treaty with them, eventually leading the Sindareen into a serious economic collapse which forced them to genuinely ask for help; in the current timeline, they used the Federation's aid to give them time to secretly rebuild their military forces and strike again. Riker orders the Enterprise to return to Betazed.

Chapter Thirty-Five

After retrieving the body of Deanna Troi from Betazed, Riker orders an autopsy to determine the cause of Death. Dr. Crusher had never been able to determine the cause of death. Now, forty years later, they discover that she was poisoned with Raxatocin, a poison that had only been developed thirteen years earlier. Riker believes that someone has traveled back in time to kill Deanna, thereby altering history. He wants to travel to the Guardian of Forever to fix it, but Data refuses saying that Starfleet regulations clearly do not permit tampering with the timeline, and that the evidence in favour of Riker's theory is comparatively slim as Raxatocin has been known to occur in nature. Riker gives in and agrees to return to Starbase 86. There, Riker appears resigned to his fate and for several days does nothing, but finally he angrily knocks over the large grandfather clock in his office and prepares to act.

Chapter Thirty-Six

When the Chance arrives, Riker beams aboard and tells Captain Tennant that he is on a top secret mission from Starfleet. He has fabricated the relevant orders and the Chance warps out of orbit. Lieutenant Dexter informs Data that Riker is missing and Data, knowing precisely what he is attempting to do, orders the Enterprise to the Forever World.



By the time the Enterprise arrives, the Chance is already in orbit. Data finally makes contact with Captain Tennant by threatening to destroy the Chance. Tennant reveals that Riker has already beamed down to the surface. Data and Lieutenant Blair beam down to the planet's surface. Riker has already stunned the scientists on the planet's surface, but Mary Mac is missing. When they arrive at the Guardian, they find that Riker has used her to access the Guardian and is currently holding her hostage. He knocks her out and Data is unable to convince him not to interfere in the timeline. Data orders the Enterprise to fire on the force field surrounding the Guardian, but it is strong enough to hold until Riker is able to leap through the Guardian and enter the past.

Chapter Thirty-Seven

Riker arrives on the Enterprise-D in the middle of one of Lieutenant Barclay's holodeck programs. After posing as a security program designed to activate if Barclay attempted to access such programs, scaring Barclay into never using the holodeck again, Riker heads to his younger self's quarters to warn him about Deanna.

Admiral Riker gives Commander Riker the antidote for the poison and tells him that Troi will be dead in fifteen minutes. He is convinced of the truth when Admiral Riker cites a few lines of the love poem that he wrote for Deanna in the Jalara Jungle. Commander Riker is ready to interfere and he races out to Deanna's quarters.

Chapter Thirty-Eight

Riker gives Troi the antidote and tells her to drink it. Dann tries to prevent her from doing so but Riker throws him across the room. Dann is revealed to be a Chameloid and Deanna drinks down the antidote just as she begins to feel a burning sensation.

Chapter Thirty-Nine

Worf brings the Chameloid to the brig while Picard, Troi, and Commander Riker return to Riker's quarters to find Admiral Riker still there. Riker tells them that he was there to save Deanna's life, but refuses to give any more details. He surmises that the Chameloid is Lt. Blair and that Deanna's life is still in danger since he is still in the past.

Commodore Data has also arrived in the past and has tricked Lieutenant Commander Data to meet him in his quarters. Barclay runs into both of them in the halls and thinks he is going crazy. When Data arrives in his quarters, his future self turns him off and hides him in a closet so that he can take his place on the ship and kill Troi himself.

Chapter Forty

Picard goes to Ten-Forward to discuss the situation with Guinan, but she is unable to tell if there are any serious disturbances in the space-time continuum, explaining that she is only 'sensitive' to changes in the past while events in the present unfold for her in the same way as everyone else. Data walks in and asks whey there are guards posted around Troi's quarters. Picard tells him the current situation.

Chapter Forty-One

Adm. Riker has concealed a miniature phaser in his heel and uses it to burn through the wall into the next room. He escapes, heading for the peace conference. Data arrives at the conference ahead of Riker and gets Troi to leave with him by telling her that Adm. Riker is near death in sickbay.

Chapter Forty-Two

Adm. Riker finds Data's head in his quarters and he tells Data- worrying that Data would side with his future self if he knew the truth- that he is an alternate version of Riker, and that the enemy is Lore who is intent on killing Troi for unknown reasons. Data can control his body remotely, so Riker leaves, carrying Data's head while Data controls his body behind them.

Cmdr. Riker realizes that Data has used a contraction and sends a mental warning to Troi just as Data is about to kill her. Riker and Picard attempt to stop Data, but due to his superior strength (and the fact that he has removed his off switch) are unable to.

Meanwhile, Troi has realized that the Sindareens are there under false pretenses and do not want peace. She shouts her conclusions aloud as Eza, aide to the Sindareen Ambassader, pulls a miniature phaser from his sleeve. But before he can kill Troi, Adm. Riker throws Data's head through the air hitting Eza in the chest. Data's body slams Troi to the ground protecting her from further attacks. Adm. Riker realizes that Eza must be from the future as well; it was he who had originally altered the past by killing Troi. Now that Deanna's life is no longer in danger, Riker, Data, and Eza fade away.

Chapter Forty-Three

Riker visits Deanna in her quarters and mentions that the Chameloid has disappeared as well. Data has told him that Adm. Riker claims that it was Lore who attempted to kill Troi, but Riker is not so sure, although he is content to allow Data to assume that version of events is the truth as he believes that Data finds it difficult to accept that any version of him could want to kill his friend. Riker has made her a present; it is a copy of the white headband Troi had at the end of Chandra Xerx's wedding. Although still unsure about their relationship, they make love and agree to give their relationship another chance.

The Beginning of the End[]

Chapter Forty-Four

The Guardian of Forever.

The four time-travelers come out of the Guardian and Mary Mac recognizes Eza as Mar Loc, the missing scientist. The Guardian says "All is ... as it was" confirming that Riker has corrected the timeline and not destroyed it; the Guardian had simply never clarified the issue for those using it because nobody had actually asked if the current timeline was wrong or not. Riker realizes that Mary Mac's unexplained bruise was a spray-hypo mark. Mar Loc must have shot Mary Mac up with something while she left and used her to access the Guardian. Data realizes that he made several clumsy mistakes in his recent trip to the past and Riker believes it was Data's unconscious at work. As they prepare to leave Forever World to find out what the 'true' timeline is like, Riker can sense Deanna's voice in his head welcoming him home.
