Nano and his older brother, Felix, are best friends who do everything together. When Felix bans Nano from his treehouse, Nano is crushed.  This is the classic story of squabbling siblings—the younger one adoring, the older in need of space. The comical illustrations brings visual humor to the storyline. A  relatable tale to big brothers and sisters everywhere. Ages 4-8.
