Bound By the Wraith: Northern Realms by AC Ruttan

Will one year with a demon really save her soul?

Cali sold her soul to save her dying husband, only to have him walk out on her. Now, the sexiest reaper has come to collect. She’s prepared for an eternity of damnation, until the wraith offers her a way out.
Be his for one year.
Mind, soul and body.
Cillian only has ever pursued power and his favors always come with a price, but being dark and evil can be lonely. Maybe it’s time for him to take a mate, and desperate Cali makes his cold blood heat with a fiery passion. He’ll bind her to him and make her forget the mortal world.
It seems like an easy way out for Cali, but can she last the year locked away in his realm?
