The Wingfeather Saga
The Wingfeather Saga is a series of four fantasy novels plus a "Creaturepedia" written by Christian singer/songwriter Andrew Peterson, consisting of On the Edge of the Dark Sea of Darkness, North! Or Be Eaten, The Monster in the Hollows, and The Warden and the Wolf King. The series chronicles the adventures and transformations of a family called Igiby, with three children, Janner, Tink, and Leeli, as they discover secrets of their family history, flee the evil beast-men the "Fangs of Dang", who are occupying the country of Skree where the Igibys were raised, seek their place in the world, and make a stand against the mysterious ruler behind the Fangs, Gnag the Nameless. The series contains some elements of Christian allegory, but is primarily a chronicle of the children's adventures rather than an allegorical journey.
