Under attack from an unseen foe, one of the coterie has vanished without a trace, and investigation seems fruitless. The loss of another ally leads those who remain to look deeper into the shadows of a conspiracy, but in the dark of night, no kindred can be trusted. Their enemy is not without a flaw, however, and the capture of an underling yields information. With a lead in hand Warren, Wren, and Jasper confront a danger that is but a taste of what is to come.
