Do your worst / Rosie Danan.

"Riley Rhodes finally has the chance to turn her family's knack for the supernatural into a legitimate business when she's hired to break the curse on an infamous Scottish castle. Used to working alone in her alienating occupation, she's pleasantly surprised to meet a handsome stranger upon arrival-until he tries to get her fired. Fresh off a scandal, Clark Edgeware can't allow a self-proclaimed "curse breaker" to threaten his last chance for professional redemption (or his traitorous heart). After he fails to get Riley kicked off his excavation site, he vows to avoid her. Unfortunately for him, she vows to get even. Riley expects the curse to do her dirty work by driving Clark away, but instead, they keep ending up on top of each other. Turns out, the only thing they do better than fight is fool around. If they're not careful, by the end of all this, more than the castle will end up in ruins"-- Provided by publisher.
