Apocalypse Orphan (The Fractured Earth Saga)

Commander Orlando Iron Wolf is aboard the International Space Station when a blinking light on his computer console alerts him to a fast moving comet headed for a collision with planet Earth. With no way to stop the impending doomsday, the world descends into panic and anarchy. Massive transport ships are built to colonize the moon, and evacuation of a chosen few begins. After a shuttle mission to study the approaching comet goes awry, Wolf is forced into cryogenic deep sleep, and the onboard computer assumes control of the ship. Wolf awakens 50,000 years later to a wildly different earth. Endowed with incredible strength, he finds himself caught in a war between primitive tribes, and his survival depends on Syn, an advanced computer intelligence who has fallen in love with him. Will Wolf be able to help restore Earth to its past glory or is civilization doomed to fail?
