Silvermist

Bob Johansson didn't believe in an afterlife, so waking up after being killed in a car accident was a shock. To add to the surprise, he is now a sentient computer and the controlling intelligence for a Von Neumann probe. Bob and his copies have been spreading out from Earth for 40 years now, looking for habitable planets. But that's the only part of the plan that's still in one piece.

Two years and 6,000 miles away from the explosion that took his leg, Josh Carpenter struggles to reclaim his former life as a college student. Mary Fischer, a civilian for the first time in years, strikes out on her own to create a new, independent life away from the army and her controlling mother. The last time Josh saw Mary, his National Guard unit was leaving Kuwait, headed north to the war. The last time Mary saw Josh, she watched as his unconscious body was rolled onto a plane bound for a hospital in Germany.
