The Darrow Brook Fairies - The Progeny is the heartfelt finale to a fantasy trilogy about tiny, immortal fairies called Darbries, who have followed their human friends from a hidden canyon to a new life in Washington State. When a catastrophic flood buries the female fairies and their eggs, a desperate Darbrie named Fly recruits Katie, an animal rescue rebel with a backhoe license, and Mr. Bob, the disabled writer who first befriended the fairies, to attempt an impossible rescue. As hatchlings grow, secrets from the original alien "pets" are revealed, young leaders like Tom Bull and Kissy Crab challenge cruel traditions, and the clan must decide how to split, migrate, and build "Safe Harbor," a school and refuge where Darbries and humans can learn to live together.
