Polo and Lily by Regis Faller

PreK-2. This wordless book is read by looking from each brightly colored picture frame to the next like a comic book. Polo is a dog and receives a special visitor one day when Lily, a bunny, crashes into his treehouse on her magic cloud. The two friends play and eat together and then Lily summons her cloud and goes home. Polo misses his friend until he realizes that Lily left him a special gift to use so that they can keep in touch.

This is a great book to use when reading together as kids are encouraged to "read" the pictures and "tell" the story. Anything goes with wordless books, there's no wrong way to tell them!
