I'm writing this despite having owned this book for the best part of a decade - in the hope of convincing you to go ahead and buy it. You won't regret it.
Nope, I'm not related to him, nor am I on some kind of percentage. It's simply a DAMN good book and you shouldn't hesitate to give it a chance. And in my mind it deserves a little better than the somewhat reserved previous review. It certainly made me laugh out loud, and I suspect you will, too.
Catch, the eponymous 27th level demon, is relentlessly evil (as, I suppose, you'd expect). Travis, the demon-keeper, isn't a bad man trying to make good. Instead he's a good man forced to be bad. By love.
The rest of the characters are all splendidly memorable too. And, as with most Christopher Moore books, it's best to abandon any attempt at trying to keep ahead of the plot. Just give up and go with the flow......
