When Ivy moves away from her home town for a fresh start, the last thing she expects is to be kidnaped and taken to an underground community full of vampires in Scotland. Assigned as the personal blood donor of the prince of the so-called 'Warren', she is forced into his living quarters, and into his bed. Angus is bored of Warren life. The humans no longer interest him, and he has a tendency to kill them before he's had the chance to commit their name to memory. But things begin to change when he suspects that his new donor isn't all that she seems. When the truth comes out, Ivy has to adapt to stay alive, and Angus must decide whether or not to help her.
