A science fiction adventure with the familiar, moderately engaging ingredients of time travel and extrasensory perception. 19-year-old Sael, a gifted but inattentive student, possesses a range of strong esp talents, but because of them he's emotionally out of control. Worse, his power of premonition has revealed a black spaceship traveling out of the future to destroy planet Galapix. Sympathetic councillor Jerik captains a Galapix ship which will dive into the local timewarp to try and intercept the bad guys before they arrive in the present; illegally, he insists on taking Sael along, to coach the lad and because Sael's powers might come in handy. Up in the future--which is evil, because the baddies have succeeded in destroying Galapix in the present--they have various adventures before Sael finally learns self-control and becomes a hero by helping to trap the invading bad guys inside the time warp. . . so the evil future doesn't materialize after all. A modestly appealing debut, with a brisk, fairly involving story and well-handled esp notions--even if the focus drifts away from Sael rather too often, and Livoni descends into pulp gibberish when describing what makes spaceships go.
