An unforgettable opening scene, in which Amy watches her parents climb into glass boxes to be agonizingly frozen alive and then submits to being frozen herself, launches this riveting thriller about space travel, secrets, murder and Realpolitik. Amy’s family chooses cryogenics so they can be defrosted when the spaceship Godspeed completes its 300-year journey to a new planet. But en route, in space, Amy’s cryo-wires are unplugged early—almost lethally. She wakes to meet Elder, another teen, named for his leader-in-training position. Ironhanded commander Eldest refuses to teach Elder the critical details for running Godspeed, and in scrutinizing the deadly mystery of who’s unplugging the frozens, Elder and Amy uncover generations of devastating lies underpinning Godspeed’s on-board society. From the ship’s windowless metal walls and recycled-air full-farming ecosystem to the people’s carnal and oddly synchronized breeding Season, Revis’ extraordinary setting is credible and palpably claustrophobic. The two teens’ alternating viewpoints, both in first person, divulge information to readers bit by tension-filled bit. Wherever the series goes from here, this opener leaves an indelible imprint.
