Vulcan's Soul

Vulcan's Soul was a miniseries of three books, written by Josepha Sherman and Susan Shwartz, and are a follow up to Vulcan's Forge and Vulcan's Heart which charts Spock's adventures in the 24th century.

Book 1: Exodus (blurb)
One year after the end of the Dominion War, the Romulan Star Empire comes under attack by a mysterious and alarmingly powerful enemy calling itself the Watraii, a species with a long-standing vendetta against the Romulans. Yet though they remain tenuously allied, the Federation, the Romulans, and the Klingons are unready to become embroiled in another sustained conflict, forcing Ambassador Spock, Admiral Uhura, Admiral Chekov, Captain Saavik, and some unexpected allies to defy their governments in order to meet the new threat head-on. But the first blood drawn may prove to be among the dearest of all.

Unknown to the defenders, the secret behind the Watraii's attack is buried in Vulcan's violent ancient past, during the time of Surak himself, when the proto-Romulans -- staunch opponents of Surak's reforms -- were compelled to take their chances among the cold and distant stars. Now Spock must begin the first leg of a long and dangerous road to learn the truth...before his hopes for the future become ashes.



Book 2: Exiles (blurb)
Tensions remain high as the United Federation of Planets, the Klingon Empire, and the Romulan Star Empire attempt to maintain their fragile post-Dominion War peace in the wake of the brutal attack by the mysterious Watraii that ended with the loss of Admiral Pavel Chekov. When Admiral Uhura receives intelligence regarding a Watraii base that may contain more than one surprise, she sends Ambassador Spock, Captain Saavik, Ruanek, Captain Montgomery Scott, and Lieutenant Commander Data on a covert mission to learn its secrets...

But the true secrets of the Watraii have their basis millennia in the past. In the time of Surak, Vulcans were at a crossroads, on the cusp of either embracing logic or succumbing to emotion and destroying themselves. With Surak's blessing, a group of Vulcans left their turbulent homeworld to find their destiny among the stars -- but the stars prove themselves even more unforgiving than the sands of Vulcan's deserts, as Karatek, the reluctant leader of the exiles, must struggle to hold the community together.
