The Wombat File Is Yours to Keep

From the customer reviews of a major book retailer comes this “student’s” opinion of a Pulitzer Prize-winning novel.

Junk
A Student, A reviewer, 11/19/2005

This book would be a decent book if the plot stuck to the back of the book, but it didn't. Half of this book is about [Protagonist]'s love life which was mind dulling. The other half is about him building up business's without any obsticals, and let me tell you it gets boring as heck. Sometimes there were chapters that had absolutly no point to them and others were chalk full of unnessary description. I just can't understand why this book won a Pultizer Prize... But over all I strongly believe that this book is better burning material then what it was intended for.

Also recommended: Not '[title of book]'

Any guesses as to the author or title? A couple of hints: it was written within the last two decades, and a subsequent short story by the author was adapted as a fairly successful film in 2006.
