Last Night I Sang to the Monster is heartbreaking, powerful and poignant. Addiction, alcoholism, and domestic violence are central to the story line. Eye-opening and thought provoking, the story of this teen addict in deep emotional pain is ultimately one of hope and healing. Subject matter is mature and best suited to older teens. Language is graphic and frequent, drug and alcohol use is prevalent, and sexual abuse/incest is referenced several times. Family is dysfunctional and abusive and mental illness in the form of depression is an issue for the main character's mother. An intense incident involving a murder/suicide takes place. An important and supportive relationship is formed between eighteen-year-old Zach and his middle-aged roommate Rafael. Writing is poetic and rich with metaphors and symbolism. Readers will root for Zach to succeed in his sobriety and to face his demons. This emotional story ends on a hopeful and positive note.
