Ally is a little girl who loves dinosaurs. She wears a dinosaur tail, has stuffed replicas of them, and pretends to eat and make sounds like them. While her parents are tolerant of this obsession, it does not make Ally's first day of school go very smoothly.

For every question, she has an answer related to dinosaurs. When Ally takes time to really listen to her classmates, she discovers that they have their favorite animals and obsessions just like her. School turns out to be a place where diversity is affirmed and enjoyed.

Writer and illustrator Richard Torry has a keen eye for the importance of openness as a key virtue for children to take to heart and to practice. Ally-saurus & The First Day of School is aimed at children from 3 through 6 years old.
