"The raw story of Frank Meeink's descent into America's Neo-Nazi underground and his ultimate triumph over hatred and addiction makes Autobiography of a Recovering Skinhead a powerful read." "Frank's violent childhood in South Philadelphia primed him to hate. He made easy prey for a small group of skinhead gang recruiters led by his older cousin. At fourteen, he shaved his head. By sixteen, Frank was one of the most notorious skinhead gang leaders on the East Coast. By eighteen, he was doing hard time in an Illinois prison." "Behind bars, Frank began to question his hatred, thanks in large part to his African-American teammates on a prison football league. Shortly after being paroled, Frank defected from the white supremacy movement. The Oklahoma City bombing inspired him to try to stop the hatred he once had felt. He began speaking on behalf of the Anti-Defamation League and appeared on MTV and other national networks in his efforts to stop the hate." "In time, Frank partnered with the Philadelphia Flyers to launch an innovative hate prevention program called Harmony Through Hockey. He is currently developing a similar program for the Iowa Chops, an AHL team affiliated with the Anaheim Ducks." --Book Jacket
