Hull Zero Three by Greg Bear-
Never one to play it safe in his consistently inventive fiction, Bear takes the reader for a harrowing ride on a labyrinthine starship in his latest hard-SF-oriented novel. Bear’s protagonist is an amnesiac starship crew member just released from a deep hibernation state called Dreamtime. Naked, disoriented, and forced by extreme temperature and gravity fluctuations to find safety somewhere among a confusing network of passageways, the man eventually receives help from an odd assortment of fellow Dreamtime refugees. Taking stock of their surroundings, while avoiding onboard killing machines, the gang quickly realizes the starship has given them each a unique role to play, including discovering collectively why the ship has been seriously damaged and cast aside from its mission to seek out habitable worlds. Bear’s pithy, occasionally cryptic writing style perfectly captures the chaotic experiences and unsettling revelations the team endures, while putting an intriguing spin on the timeworn SF theme of interstellar planet hunting. One of Bear’s most thought-provoking and well-crafted novels to date.
