Query: Well Done Thriller!

This is my first book by Tom Savage but it sure won't be my last.Mark Stevenson, author of the book Dark Desire, is sent on a scavenger hunt by the serial killer, he has written about in his novel. A couple of times I found myself thinking "come on" which is why I gave the book 4 stars instead of 5. But the story really grabs you and drags you along with it. Great ending is all I'll say!If you like thrillers and mysteries check this one out.
