In this sweet and tender picture book, a trip to the library turns into an adventure in kindness and a reminder that people experiencing homelessness deserve compassion and respect—just like every human. During a visit to the library, Brian is sure he sees his Pop-Pop around the corner—same eyes, same beard, same bushy eyebrows. Nope, that's not Pop-Pop! This man brushes his teeth in the restroom and his sneakers are patched with duct tape. Some people make frowny faces and even call him mean words, but Not Pop-Pop loves books, puzzles, and turtles, just like Brian. He may not be Brian’s pop-pop, but could he be someone’s? Not Pop-Pop also includes a kid-friendly resource for adults to begin conversations about homelessness, empathy, and ways that anyone can make a big difference in the life of a person in need.
