Wow. The Rook was not what I had expected. This book is like The Bourne Trilogy (but with a female protagonist) mixed with X-Men and Johnny English. In saying that, this book would make a fun tv show or movie. I loved learning more about the 'old' Myfanwy as the 'new' Myfanwy tried to keep up appearances after her forced amnesia and run a secret intelligence agency full of operatives with weird powers. It was hilarious in parts, scary and disturbing in others and really gripping the whole way through. I would definitely recommend this book.
