I'm more of a fiction fan, but there are a few non-fiction that stick out for me:

Rain of Gold, by Victor Villasenor. The biography of his grandparents and a great read about immigrants setting roots in America. This is one I've recommended over and over.

Just about anything by Bill Bryson & Hunter Thompson

The Shirley Letters by Louise Amelia Knapp Smith Clappe, a collection of articles written as letters from a woman in the California Gold Mines. If you've spent time in the Feather River/Plumas County area you'll enjoy it even more.
