Young, willful Princess Hilna longs to do what boys can do: ride wild horses, practice sword fighting, seek adventure. But her strict father and spiteful stepmother see her worth as nothing more than an accessory for her future husband. Then she meets Latio, a brash and mysterious warrior prince, who seems to be the only one who truly understands her. Their intertwining fates take them down a path of ruin and betrayal as dark forces bring two empires and a kingdom to the brink of war.
