In this comedic 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? After much drama, Squirrel doesn't find an answer―the friends keep coming―and he ends the book with at least three better best friends.
