Hero or scoundrel? A talented actor or a dangerous criminal? The candid, detailed autobiography of Hollywood’s “bad guy,” Danny Trejo, begins with a camera in “Folsom” and the terrifying “B” sector in “San Quentin,” and continues with an astonishing success on iconic film sets. Trejo tells his story with humor, humility, and elegance, yet he’s also openly honest about the cruelty that filled his young years. This book is an excellent proof of how we can change our own lives—even at the hardest moments—and turn pain into something beneficial.
