Query: So funny! Loved its guts!

LOL hilarious! I loved this book and laughed my way through it. Smart, fast, funny--a really great read. Warning: if you read this at the beach, you'll forget to look up and miss the sunset. Who is this Andy Schell guy? Is this really his first novel? He's so good I hate him.
