While not quite as life-changingingly awesome as Lonely Werewolf Girl , this is still a ripsnortingly fun read.

Updated to add: One of the reasons this book didn't completely work for me is that, even though it is set in New York and two of the main characters are supposedly Americans if not New Yorkers, all of the characters seemed British to me. Millar avoided any really obvious faults in vocabulary, but the tone of the dialogue wasn't quite right for New Yorkers.

Updated to add, second iteration: Now that I've thought about it some more, I can't think of a way in which making the New Yorkers more realistic would have helped this book, which is essentially escapist and non-realist, and is in no way a "gritty urban fantasy." Introducing more gritty or realistic elements would probably have destroyed what Millar was going for, if I can even pretend to know what his intentions were.
