Myfanwy comes to right in the heart of a UK park, surrounded by several corpses in weird latex gloves. She's got a letter in her hands, and it claims that her body doesn't really belong to her. She doesn't remember a thing about who she is or what she's supposed to be, so, all that's left for her to do is to follow the "manual" in the epistle and try and recollect at least some parts of herself.
Her own identity is on the line, and, given the fact that she's got nothing to lose, Myfanwy is ready to do whatever's necessary to uncover the real truth and to put down the operatives that want her dead. Soon, the lost girl figures out that she's what's called a Rook - an elite member of a super-secret organization that's fighting the numerous supernatural villains that want to bring England to its knees. It's called Chequy, and that's where she's headed.
The girl also learns that she's not just a regular human being and possesses quite a rare, dangerous and deadly ability that will turn the tide in this centuries-old war. So, she embarks on a perilous journey, hoping to uncover the scum in Chequy that exposed her and left her stranded, completely alone and vulnerable. The biggest question is - why would somebody do that and who's standing behind this evil plan?
On her way, Myfanwy meets a being with 4 bodies, a fancy woman who can be a part of her dreams, an underground lab where kids are turned into lethal killers, and a huge conspiracy that's much more sinister and devastating than she could ever think. The Rook is quite an exciting, riveting and fresh fantasy-supernatural-thriller novel. It's suspenseful, action-packed, and all-around amazing.
