Grave Attraction - Grave Desires, #4

Reaper Adam Javorski has always followed the rules while helping the dead cross into the afterlife. But when he arrives at the site of a serial killer's latest victim, finding a living-and gorgeous-prisoner is the last thing he expects. The young woman captivates him in a way no one ever has-so much so, he breaks rule number one by helping her escape. Four centuries after the death of her mate, shifter Marlena Walther has resigned herself to a loveless, lonely existence.
Imagine her surprise when she realizes the reaper who came to her rescue has the soul of her long-lost mate. But he's a different man from a very different time, with no memory of their prior life together. While the two work together to track down a killer determined to finish what he started, their undeniable attraction draws them even closer. But the killer has dark plans of his own, and if Adam isn't careful, he might become the very first reaper to lose his own soul. Originally released in 2016.
