Light the Shadows by Michelle Clay
You only get one chance at life then you die. The game’s over, no second chances. But she was never one to follow all the rules.
In a strange twist of fate, a woman flees purgatory only to jump into a newly vacated body. When she wakes in the hospital, she has a brand new life and a whole lot of unanswered questions. Now she’s Micah Munroe, a real estate agent with broken memories of the messed up life she once lived. A mysterious man who claims to be Death says she’s his granddaughter and that she’s something called a grimm.
Sully knows she’s an imposter because he reaped the soul of the real Micah only a week ago. He suspects she might be a misplaced shadow, what he calls spirits and vengeful ghosts. He becomes obsessed with finding out who she really is and just how she inhabited a new body. He’ll stop at nothing to find the truth and send her back to purgatory where she belongs. What he didn’t bargain on was how his body would react to her or how powerful the white light within her is.
When a powerful shadow and her horde of angry spirits kidnaps Sully’s best friend, they must work together to get him back. Fighting their feelings for each other isn’t half as difficult as fighting the army of shadows bent on starting a war with the living.
