Rook Audible book

I am listening to Rook it is written by Daniel O'Malley  and narrated by Susan Duerden. It is a sci-fi book. The main character is Myfanwy Thomas. She has amnesia and she is trying to find  out who took her memories away. She is a supernatural government agent called a Rook. The agency she works for is Chequy.  The members of the Chequy possesses many rare abilities, such as a person with four bodies, a women who can enter your dreams and Myfanwy abilites are by far the most interesting.
