In a snow-cloaked kingdom, two wicked rivals secretly compete for the pure heart of a prince, only to discover they might be falling for each other…

Karnawał season is a time for mischief and revelry. For the next few weeks, all will be wintry balls, glittery disguises, and nightly torch-lit sleigh-parties.

Unbeknownst to the merrymakers, two monstrous girls join the fun. Zosia and Marynka are drawn to each other the moment they meet, until they discover they’re rivals who both have their sights set on the prince’s heart. If one consumes a pure heart, she’ll gain immeasurable power. Marynka plans to bring the prince’s heart back to her grandmother in order to prove herself, while Zosia is determined to take his heart and its power for her own.

Their ambition turns into a magical contest with both girls vying to keep the prince out of the other’s grasp. But their attempts on his life draw the attention of the city that would die for him, and suddenly their escalating rivalry might cost them not just their love for each other, but both their lives.
