Harry persuades his classmates to sneak through the playground fence during lunchtime recess to view some unusual mushrooms.

"In this funny picture book exploring a forever childhood question about friendship, squirrel and a mushroom explore the forest through the seasons, show each other special trees, build snow mushrooms, share the good times and bad-which become good bad times alongside a friend. Then spring arrives, and so does a new friend. And then another. This raises a profound question for an overthinking squirrel: should we have just one best friend?"
