A Cuban-American boy must use his ability to communicate with animals to save the inhabitants of his town when they are threatened by a witch that transforms into animals. All Nestor Lopez wants is to live in one place for more than a few months and have dinner with his dad. After his dad's latest deployment, he and his mother move to a new town to live with his grandmother. Nestor plans to lay low. He definitely doesn't want to anyone find out his deepest secret: that he can talk to animals. But when the animals in his new town start disappearing, Nestor's grandmother becomes the prime suspect after she is spotted in the woods where they were last seen. As Nestor investigates the source of the disappearances, he learns that they are being seized by a tule vieja--a witch who can absorb an animal's powers by biting it during a solar eclipse. And the next eclipse is just around the corner. Now it's up to Nestor's extraordinary ability and his new friends to catch the tule vieja--and save a place he might just call home.
