She’s the head elf with a knack for saving Christmas. He’s the reluctant prince who doesn’t believe he deserves the crown—or her heart.

Alva Brightwinter is the North Pole’s fiercest and most accomplished head elf. Dedicated, efficient, and utterly unshakable, she’s spent her life ensuring Christmas runs like a well-oiled sleigh. Falling for a rakish prince? Not on her to-do list. But when magic falters and an ancient evil rises, Alva is forced to team up with Nicholas Claus, the charming, reckless heir to Santa’s mantle. Unfortunately for her, the scoundrel prince is more of a royal pain in her Cinna-bum than he is royalty—and he’s about to test not only her patience but also her carefully guarded heart.

Nicholas Claus has spent years dodging responsibility—and the weight of his father’s expectations. But when the Frost Queen threatens to plunge the North Pole into eternal darkness, the reluctant prince knows it’s time to prove he’s more than the realm’s most eligible bachelor. The only problem? His best hope of saving Christmas rests in working with Alva Brightwinter, the headstrong elf who’s immune to his legendary charm and would rather face a blizzard than his antics.

What starts as a reluctant alliance ignites into a fiery connection neither can deny. With the solstice fast approaching and the Frost Queen’s power growing, Nick and Alva must confront their fears, their pasts, and their undeniable bond. Because saving Christmas will take more than sugar plums and candy canes. It will require the ultimate sacrifice, their hearts.
