It's not easy being a young squirrel raised by a coward. At least, that's how Blossom sees her father. He's scared to leave their home. Not just the grounds of the country cemetery, Father never leaves the Sturdy Oak. He doesn't even step one toe outside. Ever! When Blossom runs away, she finds herself trapped inside the Christmas tree of the Jones family-where the decorations come to life. Blossom finds new friends in a band of handmade "lower branch" ornaments that tries to help her find her way home. But she'll soon wonder if Father was right to fear the outside world when a coterie of "upper branch" ornaments plots to rob the squirrel of her luxurious fur to fashion a coat for their leader-the angelic tree topper, Christmas Darby.
