Query: Great Concept, poor delivery.

This was my first Graham Joyce experience, and because of this book, probably my last. I gave it two stars only because it was a very light and quick read so you don't have to waste hours on a book that leaves you quite unsatisfied. First of all, I thought it was a great concept, but the actual storyline seemed painfully unoriginal. My biggest gripe with the book was that Joyce spends about 95% of the book building up to a suspenseful climax and when he actually gets to the climactic scene, he takes about a page and then the book is over. You're left with the "Did I just read all of that book for that ending?" feeling. If you come across this book in your basement (not likely since its new) and you want a quick afternoon read, this is an ok choice, but it's not worth money and certainly not worth any high expectations.
