5. Unbroken by: Laura Hillenbrand
Okay, with this one I’m breaking my rule about books being “lesser known,” because Unbroken is one of the most popular books of the past decade. Still, I had to include it on this list, because few books in my lifetime have moved me as deeply as the true story of Louis Zamperini as told through Hillenbrand’s masterful writing style. I saw the movie after reading the book, and while the movie was decent, the book is life-changing. I couldn’t put it down and I couldn’t stop thinking about it after I completed it.
