Chill

by Elizabeth Bear

The generation ship Jacob’s Ladder has barely survived cataclysms from without and within. Now, riding the shockwave of a nova blast toward an uncertain destiny, the damaged ship — the only world its inhabitants have ever known — remains a war zone. Even as Percival, the new captain, struggles to come to terms with the traumas of her recent past, the remnants of rebellion aboard the ship still threaten the world’s survival.

Yet as Percival’s relatives, Tristen and Benedick, play a deadly game of cat and mouse through a vast ship that is renewing itself in strange and dangerous ways, in pursuit of the traitor they know, an even more insidious threat is building in a place no one ever thought to look. And yet, this implacable enemy could change the face of the world forever if a rag-tag band of heroes cannot stop it.
