Five months ago, Talia Taylor finally found a job where she got to use her art history education, after years of working random office jobs. Since being hired, she constantly finds herself fantasizing about her boss, Aster. Asteroth is a bargainer demon who's been dealing in souls for the last century since he came to Earth. After hiring Talia, he's found a brightness in his life when it used to seem so filled with darkness. One evening, Aster requires her to stay late as they receive a special shipment. When one of the items isn't on the delivery slip, Aster sets out to find out what it is. Talia opens the box to find a dozen of the most beautiful rings she's ever seen. Trying on one of the rings, with the intent to buy it as a celebratory gift for getting this job, she feels pain and then warmth spreading through her body. Upon returning to Talia, Aster finds his sales assistant behaving erratically. The ring she put on is filled with lust magic that appears to be affected by her heightened emotions. The two of them need to find out how to remove the ring and the magic from Talia before it's too late-and she becomes completely driven by lust. With a lack of leads on Earth, the two travel to Hell to find a solution. Talia's rising arousal and their mutual desire for each other lead to them giving in to feelings they've both been fighting since Aster hired her. How far is Aster willing to go to save the human he's come to love? Will he strike a bargain with Lucifer to help her? When deals with the devil come with a steep price, what can he offer to make it so that Talia has the very life she laments possibly losing-even if it doesn't include him?
