Kella is a killer, but not your average serial killer, no she's one who saves women. She's a hunter who's never met a threat she couldn't handle, especially since it's the only way for a young woman to survive on the streets. That is until the day she came face to face with baddie, Ron Wolfe, who runs the city, and doesn't have any soft spots for little girls. But he decides to take her under his wing, and offer her a job with his crew, but she's still wary of letting herself accept any help from anyone, as she knows that only person she can count on herself. But there's something about Ron that Kella can't get out of her head, however, the pain from his past has become his armor, so he keeps her at arms length, and Kella finds herself getting hurt instead. Grace Between Mercy was a story that instantly transported me into the brilliant S. Ferguson's dark underworld, and when it was over, I found that I didn't want to leave. It was one wild ride with twists & turns around every corner that had the f-bombs dropping fast & furious, with an ending that kind of left me hanging even though Kella & Ron were basically wrapped up, so I have to add her to the list of author's trying to kill me dead, while hash tagging her #EVILWHORE forevermore! Now, Ron & Kella had a push & pull that was seriously frustrating but it made their sexy times very explosive which had them lighting the sheets (& random furniture) up when they did go off! And the colorful cast of secondaries made for hilarious moments that had me laughing not to mention more excitement & action! I loved every moment of this story, and hopefully there is more to this series after that ending so I will be waiting impatiently, and I HIGHLY HIGHLY HIGHLY RECOMMEND!
