There are some things an angel shouldn’t do… 

Renatus is a legalist and knows the rules better than most. But knowing the Law doesn’t stop him from imagining the press of a hard male body against his, or remembering one forbidden kiss that left him hungry for more. He leaves Heaven to mingle with mankind, hoping that satisfying curiosity will quell desire. He finds Adam, a college professor who has given up on love. 

Adam once dreamed of finding the perfect man and settling down. His dreams and trust were shattered when he found out the truth about his ex. Meeting Renatus seduces Adam into taking another chance on love. But Ren is keeping secrets, and the only promise he will make is that he will leave. 

Now the Most High has commanded Renatus to retrieve the Law of Men and 
Angels, and a vengeful demon is circling, waiting for her opportunity to strike. Staying is impossible, leaving unbearable, and Ren wants to succumb to temptation, forsaking eternity for a life on Earth with Adam.
