Last Night I Sang to the Monster by Benjamin Alire Saenz
Grab your tissues, ‘cause this one’s a tear jerker. In place of his senior year of high school, Zach is in rehab. He doesn’t remember why he’s there, so we learn about his circumstances as he works through remembering in group sessions, talking with his roommates and his counselor. What makes this book so powerful is that Zach, despite his addiction, sadness, and loneliness still manages to be a neat kid. You really want to see him succeed.
