Sugar Plum Fae by Jamie K. Schmidt

She’s the Sugar Plum Fairy. He’s the King of Nightmares. And they’re about to make the holiday season wickedly sweet.

Candace, the vivacious Sugar Plum Fairy, and Roderick, the brooding King of Nightmares, have always been at odds. But when a mysterious malaise grips the small town of Whitlock, leaving its supernatural residents listless and joyless, these sworn enemies must join forces. Their solution? A magical wishing well to reignite hope and desire in the townsfolk.
As they craft the well, Candace and Roderick strike a dangerous bargain: whoever grants the most wishes aligned with their nature – sweet dreams or dark desires – will claim control of Whitlock. But their competition takes an unexpected turn as stolen glances and heated arguments give way to undeniable attraction.
But when ancient dark magic threatens to destroy their beloved town, Candace and Roderick must put aside their centuries-old rivalry to unravel the mystery. With a vampire mayor, an army of candy warriors and stampeding gummy bears, they get locked into a face off against a power-hungry coven. Candace and Roderick must rely on each other to protect the town they’re fighting over.

As the battle for Whitlock’s fate rages, Candace and Roderick discover that the greatest wish of all might be the love they never saw coming.
