From Library Journal: "Myfanwy (rhymes with "Tiffany") Thomas wakes up in a London park surrounded by dead men, all wearing latex gloves. She has no idea who she is or how she got there. She finds two letters in the pocket of her jacket from her body's former owner. The first tells her the body is now hers and warns of danger. Myfanwy is a Rook, a high-level operative in a clandestine security force charged with protecting Britain from supernatural forces, and there's a mole in the organization who's trying to kill her. Possessed of her own supernatural powers, underestimated until now, Myfanwy proves unexpectedly resourceful and is soon kicking butt with the best of them. The pace never lets up in this entertaining high-action read. First-time novelist O'Malley has fashioned a near-perfect supernatural thriller. Don't start this book unless you've got lots of time, because you won't want to put it down. It's that good."
