We're pretty sure Nicola Yoon has mastered the page-turner with this book. The chapters are so short—the longest chapter might be eight pages—and the plot is so compelling that it's almost impossible to put down. Even the complicated philosophical discussions and miniature history lessons are written in simple, understandable language. It's an easy, breezy, beautiful book to read, although we can't promise your heart won't take a beating along the way.
