Fifth Grave Past the Light by Darynda Jones
Charley Davidson may not look like your everyday, run-of-the-mill grim reaper, but she has vowed to reap grimness wherever she goes despite this unfortunate fact. Sadly, she gets sidetracked when the sexy, sultry son of Satan, Reyes Farrow, moves in next door. As he is the main suspect in her arson case, she is determined to stay away from him until she can find out the truth. According to her therapist, however, she lacks conviction.
When dead women start appearing in her apartment - lost, confused and terrified beyond reason - Charley has no choice but to ask for Reyes's help, especially when it becomes apparent that her own sister Gemma is the serial killer's next target. With his ability to observe incorporeally, surely he can find out who's responsible. And even if he can't, he is the one man alive who could protect Gemma no matter who or what came at her. But he wants something in return: Charley. All of her - body and soul. And to keep her sister safe, it is a price she is willing to pay…
I give this book 5 chocolate dipped strawberries and an unlimited amount of shampoo and conditioner. Toilet brush as a hair brush is just wrong (but funny,which makes it ok as long as it doesn't happen to me.)
