After generations of living in a purple dogwood, Zwi's hive needs to find a new tree to call home. The honeybee has been searching everywhere for a tree blessed by the All-Being, while her squirrel friend, Witch-Hazel, tags along. But then Witch-Hazel begins seeing visions of her long-lost, beloved otter friend, Fish-Breath, guiding her on a journey toward the All-Being's castle in the sky. To complete their quests, the honeybee and squirrel must seek favors from a mysterious Luna moth, brave the temptations of a unicorn's garden, and avoid being drawn into the ongoing rivalry between a flock of ravens and a golden eagle living on the stem of giant beanstalk stretching into the sky. If the honeybee and squirrel can hold the course, they just might learn the secret behind why the endless rivers between the earth and sky dried up long ago and heal a timeless wound to their world. But most importantly, maybe Witch-Hazel will get to see Fish-Breath again.
