The Feywild Job by C. L. Polk

Sparks fly when bitter exes are forced to team up for an elaborate Feywild heist, in this cozy fantasy romance by the bestselling author of the Kingston Cycle and Even Though I Knew the End.

Saeldian has sworn never to fall in love. That oath isn’t just a personal promise, but rather a magical pact, granting them powerful abilities. The only catch? They must never give their heart away—a deal that Saeldian is perfectly content with. They’ve seen firsthand how messy love can get.
Saeldian prefers their no-strings-attached life as a con artist, pulling off heists and leaving a trail of broken hearts behind them. But when a grift goes horribly wrong, they catch the eye of a mysterious patron with a job offer they can’t refuse.
The mission? Steal a gem called “The Kiss of Enduring Love” and return it to the Feywild. Simple enough, until Saeldian discovers their ex-partner, Kell—a charming bard—is part of the team.
The last time Saeldian saw Kell, things hardly ended on good terms. A kiss became a betrayal, leaving Kell hurt and confused for almost a decade. But Kell can’t just walk away—not when this job might finally be his ticket back to the Feywild.

Forced to work together again, their adventure takes them from high-society parties to Feywild couple’s therapy. But as Saeldian and Kell rekindle their chemistry, they realize the gem is much more than a fey bauble, and their simple heist has summoned powerful enemies. . . .
