An 1880's coal town is no place for a girl with antlers.
Once upon a winter's day, a childless miner and his wife find baby Sabella in a mysterious basket. When she suddenly grows a pair of silvery gray antlers, they hide her from the world in embarrassment and fear.
Seventeen years later, Sabella's life is nothing but housework and loneliness-but charming, nineteen-year-old Calder arrives on her doorstep determined to change that. He knows her secret and has plenty of his own. Among them: he's been her unseen protector for years, he has the wings of a moth, and he's part of the Springborn: a group of people with extraordinary gifts like theirs.
As Calder strives to win Sabella's heart and the Springborn welcome her with open arms, disaster strikes. She and Calder must work together to save their exceptional family from an unlikely enemy-and in doing so, discover what it means to be true to themselves, their gifts, and each other.
