This Book will Save Your Life
A.M. Homes
2006

Certain books are awkward to read on the bus: Valley of the Dolls (because the cover is pink and it's Valley of the Dolls), Gone with the Wind (what if people think you're a confederate?) Lorrie Moore's Self-Help (it's not).

Anyway, I didn't read a single page of This Book will Save Your Life on a bus or waiting for a bus, but I did read it on the light rail and had to assure one man that it was a novel and not a cry for help.

Unlike Valley of the Dolls, which is best consumed in your home, This Book is worth the risk.
It's the second book in a row that I've had a hard time putting down. Just try not to look sad when you're reading it.
