Thanks to everyone who recommended this book. It was fantastic. I read it like a crack head needing their next fix. I devoured all 400+ pages in about 5 days.
One rainy afternoon Myfanwy Thomas wakes up in a park and she is surrounded by dead bodies. She doesn't know how she got there, or even who she is. She finds a note in the coat she is wearing, telling her what her name is, and that she has the choice to go and live under an alias, knowing she will never find out who erased her memory, or to continue to live as Myfanwy Thomas and find out who did this to her. Luckily for us, she picks option two.
It turns out that Myfanwy works for a branch of the British Government that is in charge of the supernatural, and more importantly, keeping the general public unaware that the supernatural exists. Also, most of the employees have supernatural abilities. Myfanwy can manipulate other people's nervous systems. Basically, she can kill someone with her mind! The old Myfanwy had to directly touch people to do it, but she was also a bit of a wuss. The new Myfanwy is a total bad-ass. Even better, she's a smart-ass.
This is a great sci-fi detective story, with tons of interesting characters. Of course there is room for a sequel, but I would definitely read it. This is the book that Miss Peregrine's Home for Peculiar Children desperately wants to be.
