Book excerpt: Kilmer shares the stories behind his most beloved roles, reminisces about his star-studded career and love life, and reveals the truth behind his recent health struggles. Kilmer has played so many iconic roles over his nearly four-decade film career, but here he steps out of character and reveals his true self. While containing plenty of tantalizing celebrity anecdotes, the book is ultimately a deeply moving reflection on mortality and the mysteries of life. -- adapted from jacket
