Similar to Brass' others, this novel seems to have an interesting idea, but has trouble figuring out what to do with it. We learn (frequently) that Allen's penis is small, but we know absolutely nothing about the 'warlock' who leads him into a new life -- who he is, how the ridiculously stupid rube got involved in a supernaturally high-power game, nor what his powers even are. Nor do we understand why Allen was able (or why he'd even want to) join up into that same lifestyle.
This seems to be a novel about a Faustian deal, but we never are let in on how the deal works, why it works, who is chosen or really anything else. But we are told that Allen's penis is small.
In spite of the fact that the plot was fairly non-existent and full of holes and all but one character is completely unknown to us, I did enjoy this book as a quick read. Not highly recommended, but a good way to pass your time while waiting for a plane or train.
