Sisters Addie and Clara have just moved to a new house in the country, where they discover that their backyard is a gateway to the enchanted realm of magical butterflies called Wishing Wings. These special butterflies have the power to make wishes come true! Addie and Clara are finally settling into their new neighborhood when they meet a boy named Oliver, who seems to be having trouble making friends. Then, the butterflies that Addie and Clara helped -- Sky Dance and Shimmer Leaf -- tell them that a New Bloom butterfly named Blue Rain has just emerged and is acting grumpy and mean to everyone. Surely it's the dark enchantment that's been cast at work . . . but just who is responsible for this? It's up to Addie and Clara to not only help Oliver and Blue Rain unite, but to also find out who's been working against the New Blooms.
