The Sun and the Starmaker by Rachel Griffin

There once was a village so far north that most considered it the top of the world... and in that village, the Sun fell in love with her Starmaker. From the New York Times bestselling author of The Nature of Witches comes a whimsical and sweeping romantic fantasy.

Nestled deep in the snowy mountains of the Lost Range, the village of Reverie is a small miracle. Beyond the reach of the Sun, Reverie is dependent upon the magic of the mysterious Starmaker: every morning, he trudges across a vast glacier and pulls in sunlight over the peaks, providing the village with the light it needs to survive.

Aurora Finch grew up on tales of the Starmaker's magic, never imagining she'd one day meet him. But on the morning of her wedding, a fateful encounter in the frostbitten woods changes everything. The Starmaker senses a powerful magic within her and demands she come study under his guidance. With her newfound abilities tied to the survival of the village, Aurora is swept away to his ice-covered castle and far from everything she's ever known.

The Starmaker is as cold and distant as the mountain itself, leaving Aurora to explore his enchanted castle alone. Yet the more she discovers about the sorcerer, the stronger their attraction grows, pulling her closer to the secrets he refuses to share. But a deadly frost approaches and Aurora must uncover what the Starmaker is hiding before she is left in an endless winter that even the Sun cannot touch.
