Letters to a Lifer provides a rare insight into life without parole (LWOP) for juveniles in the USA.
A true story from Pennsylvania, it is a compelling tale of faith and redemption.
Cindy Sanford tells how a chance correspondence with Ken, a prisoner artist, began to change her entrenched ideas about offenders.
Her book now adds voice to the work of the USA's National Campaign for the Fair Sentencing of Youth and will also be of interest to students of restorative justice.
In 1999, America's Most Wanted broadcast details of a notorious crime.
Twelve years later Cindy was introduced to Ken, one of the two boys convicted, through his remarkable wildlife art.
By then a young man, Ken had spent half his life in prison.
Initially wary, Cindy was surprised to find him humble, polite and deeply grateful for her interest.
Gradually she and her family were able to look beyond his crime to the person he had become.
Despite a hardening of attitudes generally towards offenders in the USA and other parts of the western world, Letters to a Lifer shows why the campaign against LWOP sentences for juveniles is nonetheless gaining momentum.
