Ruby, an orphan born without a wolf, is branded an outcast but secretly carries the rare "Little Red Riding Hood" bloodline—giving her healing, curse-breaking, and foresight—yet she's forced into servitude by the Ice Wolf King's mistress, abused, and robbed of her only heirloom by the mistress's daughter Abigail.
Desperate, Ruby escapes and is adopted by the Fire Wolf King and Queen, becoming their beloved princess; she uses her powers to heal, break curses, and foil the Ice Wolf's plots, winning her new family's trust.
Then Abigail arrives with the stolen amulet, posing as the lost princess—leaving two princesses, one truth, and Ruby fighting to reclaim her place before it's too late.
