When author Caitlin Shetterly saw an influx of license plates from Massachusetts and New York arrive in her home state of Maine during the pandemic, inspiration struck for her debut novel. Pete and Alice in Maine follows a couple that moves the family out of New York City during the initial COVID-19 scare — but finds the baggage from Pete's affair and Alice's questions about her purpose follow them. In today's episode, Shetterly speaks with NPR's Scott Simon about the very complicated idea of forgiveness, and how it eludes both of her characters.
