This book was a fascinating study of the side-by-side lives of two men with the same names but very different futures. Their lives begin in the same neighborhoods yet one ends up in prison and the other in prison for life.
The incarcerated Wes More speaks of the necessity of recognizing the difference between a second chance and a last chance. This distinction is pivotal to the story. Both young men face those second chances and by the grace of God the author uses his second chances to progress in life. The book truly does show the truths in the "There but for the grace of God go I" sentiment.
I would also point to the strong religious convictions shown by the author's grandparents. In my experience, the reformed faith is effective in grounding God's children in the truths and blessings of His sovereignty. Soli deo gloria!
