I like books with meta narratives. I also like puzzles, and this book entangles both in quite a clever way.

It also teases the reader by throwing in pieces of information that are obviously pertinent, and avoids explaining them for as long as possible, or flat out tells the reader that a conclusion turned out to be false, but again not explaining why for as long as possible.

If any of the above sounds tantalizing, this book is for you.
