This is the second Christopher Moore book I've read, but it was certainly enough to get a handle on his typical plot line: Random guy gets involved in a strange situation he can't understand that relates to some type of odd deity, he falls for a very attractive girl who is involved in the weirdness, after very silly plot twists the couple find a way to "ride off into the sunset" together. While this type of explanation would usually put me off reading more of his books, his writing is done so well and the stories so inventive and hilarious that I can't help but enjoy them.
This book is about hump back whale researchers living in Hawaii, and while I'm no marine biologist the facts all seemed very well researched. A group of researchers are involved in figuring out why the hump backs sing and what they may be saying to each other, which throws the head researcher into a crazy adventure he could never have imagined. The hot girl is a research student working with the team, but she turns out to be much more. The plot is just so ridiculous you can't help but feel entertained.
If you're looking for something smart and funny, I would definitely recommend you give this a read. I give this book 4 out of 5 stars.
