Some writers take unorthodox paths to success; for Joe Loya, author of The Man Who Outgrew His Prison Cell, that path includes a childhood full of spiritual, sometimes violent and tragic, twists and turns, followed by a stint as a bank robber known as “The Beirut Bandit.” He spent seven years in federal prison, where a months-long stint in solitary confinement led to the epiphany that began his writing career. A born storyteller, Loya covers all of it — and sets a GrottoPod record for colorful language — on this week’s show.
