Rowan Greenleaf is on the run. From who or what, she has no idea. All she knows is that they killed the only person who ever cared for her, and now they are coming for her. And, just when she thinks that things couldn't possibly get any worse, Rowan is pulled into a world that she never knew existed by a creature who shouldn't be real. Now, Rowan is in their world, and the only person that she has to depend on is Killian, the faerie that saved her, but who also sucked her into a world that's much more dangerous than the one that she left behind. Killian seems trustworthy, but everyone has their secrets, and when Rowan is separated from Killian, she is forced to rely upon the dark and mysterious Ciaran, a faerie who has secrets of his own.
