Captain Roksani Price wakes up with missing memories, broken knuckles, and a fist-sized dent in her bedroom wall. The mysterious sickness is back. She's wanted by the mafia, the military, and every bounty hunter this side of the galaxy, and Rox doesn't need any more trouble. Ashrael is on the run from a ruthless man who would unlock her genetic secrets. The Halifax is a fast ship to freedom, its crew easily won over. The captain may see through her lies, but a little blackmail can go a long way. Despite deadly illness and power-hungry tyrant, with half of humanity gunning for them, Rox and Ash always stay one step ahead. But the real danger isn't any of these things. It isn't anything they can imagine. From across the galaxy, something has been watching. There's an invader coming. Silent, undetectable, and lethal. The hunt is on.
