Jeannette Walls’ memoir The Glass Castle became an international bestseller that sold over 5 million copies. Walls’ father Rex was an alcoholic who dreamed of inventing a gold-detecting gizmo that would make him rich enough to build a glass castle. The family moved around a lot, usually before the rent came due. At one point Jeannette and her siblings were left at their grandparents’ house where they often had to scrounge food from garbage cans. Now Walls has written a novel called Hang the Moon. about a gutsy young woman who becomes a rum runner during Prohibition. We talk about what it’s like to grow up poor and how your life changes when you become very, very rich. “Now What?” is produced with help from Steve Zimmer, Lucy Little and Jullian Androkae. Audio production is by Nick Ciavatta.
