Query: Fun and entertaining!

Jim Keeble is so talented that I won't deign to compare him to that other lad-lit writer. Men and Other Mammals tells the story of Scott Barron, a bestselling author and toast of London. His life couldn't be better - that is until his girlfriend leaves him and his third book doesn't reach the same success that his previous efforts had. To make matters worse, he's begun to envy his younger brother's life. Hasn't it always been the other way around? After all, Jes is a struggling writer with an average life. But Jes, unlike Scott, is happily married. Is love the one thing missing in Scott's life? There are some fun twists in the novel.I know critics have put lad-lit writers through the Nick Hornby test. (Oops, I've said it!) But Keeble has wit, insight and self-deprecating humor all his own. I for one look forward to his next effort.
