I loved this book, it's fast paced, well written and quirky. The main character is brilliantly written, he feels like a genuine person with fears and hopes. His backstory is sufficiently tragic, but it's not dwelled upon and feels more like part of his history rather than an excuse to whine.
The main female character is brilliantly done and the relationship between the two drives this book forward.
The plot is well written and exciting, there is no point during this book that I rolled my eyes or skimmed a page. I was gripped from the start to the finish.
If you love reading stories about secret passages, conspiracies and murder then you'll love this book.
