John’s memoir

John’s story

At just 17, John Carter was a rising enforcer in the mafia — until a point-blank gunshot to the back of the head changed everything. The doctors said he would never walk or talk again.

But John always gets back up — even with nine bullet fragments permanently lodged in his skull.

This is how he battled through disability, depression, addiction, and prison to lead a life of service.

This is his story.

  • John shares his life story with unflinching honesty—his struggles with addiction, surviving a near-fatal gunshot wound, and rebuilding his life after prison. What struck me most was his ability to reflect on his past without self-pity, instead focusing on the lessons he’s learned and the people who helped him along the way.
