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. Unknown to the defenders, the secret behind Watraii's attack is buried in Vulcan's violent 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, staunch opponents of Surak's reforms, left their turbulent homeworld to find their destiny among the stars. But the stars would prove unforgiving than the sands of Vulcan's deserts.... Now Spock must begin a long and dangerous road to learn the truth about the Romulans' early history. Joined by Captain Montgomery Scott and Lieutenant Commander Data, he and his allies reach across a gulf of both time and space in an attempt to bridge the gap that separates the long-scattered offshoots of the Vulcan people. And though the reunification he hopes to achieve will come at a terrible cost, failure could mean centuries of sorrow and chaos for untold millions. Includes Exodus, Exiles, and Epiphany.
