Eleven-year-old Eleanor is always exploring the woods in her backyard, searching for new discoveries. But one day something unexpected happens: she finds herself transported to a strange and enchanting world called the Togetherwood. She meets others who have also become lost: Dax, an excitable Labrador retriever, and Claire, a prickly tabby cat. Aided by many of the animals who live there, Eleanor, Dax, and Claire make their way through the Togetherwood to find a way home. In the face of the dangers and trials along the way, will the power of their friendship be enough to save them? And perhaps save someone else, too?
