Moss, a young crow-boy, is the Protector of the Fernbough Forests. He wanders the woods and does his best to maintain the balance of the world around him. It's hard work, made even harder by the recent loss of his best friend and fellow Protector Ward. Still, Moss works himself to the bone in order to serve his community as best as he can. When a massive storm comes to the forest, threatening to destroy the life Moss has built on his own, he turns to his community in hopes of keeping everyone safe. During the storm however, a new kind of magic begins to brew, and Moss finds himself transported to a mysterious forest far away from everything he's come to know. As forces of darkness and destruction rage around Moss, he must decide what he really needs. To save this forest from a raging disease– and to find his way home– Moss will meet the unknown with his magic, friendship, and a forever-shifting world with a new outlook on what family means to him.
