Get Him Back - Coralee June

From CoraLee comes a second chance workplace romcom with a dose of revenge and irresistible passion.
Meet Jack Thompson: charming, captivating, and my newest co-worker-the same man who heartlessly ghosted me in college.
Now, it's payback time.
With a sly smile and a plan for revenge, I'm ready to make him suffer. I seduce him, unravel his world, and leave him craving more.
But to my surprise, Jack revels in the torment, finding a twisted pleasure in our vengeful escapades.
I'm not sure who's being played at this point.
I thought I had the game plan down to a science. But sometimes the line between revenge and passion is blurred-and in the biggest plot twist of all, settling scores might just mean falling head over heels.
