When the Winter arrives, the Wolves will come down over the walls and eat little boys in their beds. Doctor Nicholas Blake might still be afraid of the dark, but the monsters his grandmother tormented him with as a child aren't real. Or so he thought...until the sea freezes, the country grinds to a halt under the snow, and he finds a half-dead man bleeding out while a dead woman watches. Now his nightmares impinge on his waking life, and the only one who knows what's going on is his unexpected patient. For Gregor it's simple. The treacherous prophets mutilated him and stole his brother Jack, and he's going to kill them for it. Without his wolf, it might be difficult, but he'll be damned if anyone else gets to kill Jack--even if he has to enlist the help of his distractingly attractive, but very human, doctor. Except maybe the prophets want something worse than death, and maybe Nick is less human than Gregor believes. As the dead gather and the old stories come true, the two men will need each other if they're going to rescue Jack and stop the prophets' plan to loose something more terrible than the wolf winter.
