The Highlander’s Fury by Maeve Greyson

An immortal Fury nearing burnout from vanquishing evil. A raging Highlander determined to remain miserably alone. The goddesses’ plan to save them both with the greatest magic of all.

An average day in the life of an immortal Fury: flex powers, locate evil, administer justice. Until Ciara’s goddess mothers convince her to seduce a brooding mortal. All she must do is swap places with his betrothed. Her assignment is simple: become the seductive wife, bear the man a child, and train the young one in the Ways. Once the boy reaches seven years of age, they’ll swap her back with the wife he thinks he selected and Ciara can resume her job of rousting wickedness from the realities.
Chieftain Faolan MacKay’s advisors plague him daily about his matrimonial duties, dragging prospects from across the Highlands: plump dowries attached to each one. Faolan has lost everyone he has ever loved. He’d rather go straight to the fiery pits of Hell than down the wedding aisle. Out of desperation, his plan takes seed. He’ll select a wife he can ignore. There’s just one problem with this foolproof theory. Nobody ignores Ciara. Against his better judgment, he’s enthralled with the woman, and to Ciara’s surprise, this strange thing called love burns hotter than her hunger for vengeance.

At the end of the seven years, the ruse is up, and all will return to as it was before. Can Faolan and Ciara’s bond overcome the mandate of the ultimate powers?
