In this book, Yancey exceptionally expresses hopelessness, desperation and loneliness. He is a brilliant story-teller with the ability to make readers experience the story first-hand because he uses the first-person point of view. I love how the book is set in a wartime-like setting--broken buildings, fallen ceilings, cracked floors, and rotting corpses that lay unburied. The author makes death seem ubiquitous to the Cassie's environment. The mystery of finding out what the fifth wave is, is what kept the fire of my attention burning bright.
