Elissa Blue: Book One of The Winged by T.K. Perry
Though she worried it might never happen, Elissa Blue finally has her wings. Now she must migrate to the Mating Mountain, find a husband, and get back down the impassable cliffs before she loses her ability to fly forever. If she doesn’t succeed, she’ll be stranded as a servant in the Old Castle for the rest of her life. And if she doesn’t choose her man wisely, she will be just as miserable.
