A feel-good picture book about best friendship told with dry comedy and an open ending―squirrel and mushroom are best friends until another best friend comes to play. This morning when I was out walking, I found a best friend. At least I think so. It certainly looks a lot like it! He really has a best friend kind of face. 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 should we have just one best friend?
