Immortally Yours — J. Morgan

Cursed to live forever, private detective Chase Michaels has heard of love at first sight, but never love at first gun shot. That's exactly what happens when Belle Gardner, the woman he's been paid to find, pumps three shots right into his chest.
Drawn into a dark world where fairytales walk the earth and things are seldom what they seem, the pair find themselves on the run from her not-so-husband, evil sorcerers, and two warring armies of Sidhe all aiming to wipe them from the face of the earth. Torn between fighting for his life, and giving in to the truth that Belle has unlocked a part of him that he never thought existed -- his heart -- Chase stands at a crossroads in his long life.
Does he protect the only person who might stand a chance at breaking his curse, or does he discover if he can stand being immortal if it means losing the one thing he's never had -- true love?
