Hull Zero Three (Greg Bear)

A mysterious, intriguing tale of a man who wakes up (or is created) on a giant interstellar ship in mid-voyage and must figure out what is going on. The ship is obviously damaged and malfunctioning: heat and gravity are erratic, monstrous things keep trying to kill him, and he is plagued by a faulty, untrustworthy memory. He finds others he thinks he can trust, and together they try to solve the mystery of the ship, its past and future. The mysteries were explained in the end, which made the story worthwhile. I enjoyed it, in a dark and frustrated kind of way. The author definitely accomplished what he set out to achieve.
