Three young sisters share a bedroom but have very little else in common. When their constant arguing over rights to the room becomes too much for them, they devise a contest: Whoever makes their mom the best birthday present will be declared Queen of the World and will rule the bedroom. However, all their scheming makes a mess, and instead of making their mother happy on her birthday, they actually make her cry. Will the sisters be able to figure out what gift their mom wants most of all? Color illustrations accompany the text.
