A young boy discovers that having a whale for a friend makes anything possible in this touching picture book from the illustrator of Night Night, Groot! Sometimes Tim feels invisible at school-until one day, when Tim meets Sam. But Sam isn't just any new friend: he's a blue whale, and he can't find his way home! Returning Sam to the sea is hard work, but Tim is determined to help. After all, it's not every day you meet a new friend!
