The Rook is a surprise.
It starts with a puzzle, and this puzzle gets taken apart throughout the book, where more and more becomes clear. This happens in many books, but the way Mr O’Malley did this is master-crafted.
A strange awakening, mysterious letters and amazing powers that unfold in more and more people are a touch of The Rook. If you like fantasy and supernatural powers, stacked up on a nice mystery, you will do yourself a favour by reading this book.
