I really enjoyed this book. Dark, chilling and well-written. Since reading it I have gone on to read the others in the series - The Disciple, Deity, The Unquiet Grave and Under A Killing Moon and loved them all. In fact they get better and better as they go along.
Damon Brook is an interesting character, flawed enough to make him really interesting.
I cannot recommend this series of books highly enough and The Reaper is a brilliant opening book.
