Driving Sideways by Jess Riley (2008)

Driving Sideways is about Leigh, who just recovered from a kidney transplant, and is taking a road trip from her native Wisconsin to try to find her mother in California. Riley has a beautiful Midwestern voice, and fabulous humor. There are at least four laugh out loud moments on every other page of this hilarious novel. Plus, it's poignant and touching as well. SO good. So so so good.
