"Maple & Willow Apart" by Lori Nichols

Maple and Willow have spent all summer together and it's been great but school has started and Maple begins kindergarten and enters a fascinating world of new experiences and friends. While Maple's at school Willow is all alone and things just aren't the same. Until the day she meets Pip. Maple tells about her school adventures and Willow talks about her days with Pip. But something's wrong. Maple starts to feel left out and when Pip teaches Willow to ride on a huge snail, things come to a head. But Willow has a great idea, one that will let the sisters continue to share their best times even when they aren't together. Loved this book, sweet with a great imaginative look at a child's invisible friend situation and willingness to share.
