Ciara, Immortal Fury, spends her days locating evil and administering justice. When her goddess mothers inform her they need a gifted child, Ciara agrees to their plan. She will swap places with Faolan MacKay's shy bride long enough to conceive, bear, and train a child in the old ways, before resuming her duties as avenger of wickedness.
Laird Faolan MacKay's advisers are pushing him to wed. Faolan has lost everyone he's ever loved and would rather travel to hell than down the aisle. To silence his advisers, Faolan chooses a woman rumored to be meek and easy to ignore. One problem: Nobody ignores Ciara. Against his will, he's enthralled with his new wife - to Ciara's surprise, the mortal affliction called love burns hotter than her hunger for vengeance. But when their time is up and Ciara must leave, can the bond of love overcome the edict of the ultimate powers?
