The word “postmortem” is sometimes adopted to refer to a conversation about why a relationship ended. With this in mind, Tom McAllister’s new novel The Young Widower’s Handbook might be called the ultimate postmortem. The novel follows 29-year-old Hunter Cady as he takes a road trip across the country with the ashes of his late wife, Kait, and reflects on their relationship along the way. It’s heartbreaking and funny and has earned itself a spot on the spring 2017 Barnes and Noble Discover Great New Writers list. I caught up with McAllister, who teaches composition and creative writing, to talk about the novel, his podcast, and why he hates driving.
