Soul Survivor — Katana Collins

With immortality comes a craving that can't be satisfied, a need never fulfilled. . .

Once an angel, now a demon, Monica is still a succubus with an insatiable desire for sex. The more the better. Soul-stealing orgasms beat out dealing with her broken heart any day of the week. Monica has no interest in being near both her ex-lover and his new girlfriend, so she's not thrilled when she's asked to join them in investigating a string of murders that are clearly beyond the pale. But when she sees that one of the victims has her Celtic family crest carved on his arm, she realizes she may finally find the answers to her past she's been searching for all these years. . .
