On one brisk, chilly day, Arnold the bear is determined to stay inside and make popcorn balls. But his best friend, Louise the chipmunk, wants to be outside and make leaf piles. After all, the leaves have finally fallen to the ground, bringing the first day of what Louise calls fell, the season between fall and winter. An argument ensues, so they decide to do their preferred activities separately. But when they both realize that one thing is missing—each other—can they find a way to celebrate together? Exciting, easy-to-read books are the stepping stone a young reader needs to bridge the gap between being a beginner and being fluent.
