Self-help ✦ Penny’s Take
The Thank You Book
Mo Willems · 2025
88/100
👍 Worth It
Mo Willems sticks the landing on 25 books with a finale that is genuinely clever — a parade of every friend from the series culminating in the reader themselves being the one Piggie almost forgot. That meta-joke lands for adults reading aloud just as well as for children who have grown up with Gerald and Piggie. Two Theodor Seuss Geisel Awards for the series says everything you need to know about the craft; this is early-reader writing at its best.
