Ken Guidroz is the author of "Letters to My Son in Prison". 

At one point, Ken was a pastor, and he never thought he'd have to worry about his kids ending up in serious trouble, let alone prison. After his middle son, leading a wayward life, became addicted to heroin, this led to a car crash resulting in the taking of another man's life. That led to a series of letters to his son in prison, a road for their own reconciliation, and a rebirth and strengthening of faith for both.
