Fentanyl does not contain a single gram of mercy. So says Joe Calendino, former full-patch Hells Angel and now Executive Director of Yo Bro Yo Girl Youth Initiative. In To Hell and Back 2: Addiction and Recovery, Calendino shares how, strung out on cocaine and a cocktail of other drugs, he once lived deep inside the hell of addiction. Through his own efforts, and the support of a few dedicated "hidden angels, " Calendino kicked his habit and committed the remainder of his life to helping others kick theirs.Building on the popular memoir To Hell and Back, this sequel examines today's rampant drug nightmare through various lenses. Interwoven with Calendino's own story are those of various others: families who have lost loved ones due to drug overdose, friends whose drug habits have ripped their lives apart, sometimes landing them in jail, sometimes at the end of a loaded gun, even a young man currently facing a murder charge tied to gang control of the greater Vancouver drug trade.Despite this landscape of struggle, To Hell and Back 2: Addiction and Recovery leaves the reader hopeful. As long as someone struggling with addiction draws breath, there is hope. As long as "hidden angels" maintain ties, that person can leave the hell of addiction behind.
