The book starts out with Grace (a witch) summoning Crown Prince of Hell Caspian. They are instantly attracted to one another, but Grace tries to play it off like she's not impressed by either Caspian's sexiness, or his power. Grace is doing this summoning for revenge. Her ex is a total creep and he has taken and kept their young son from her. Later in the story she is told that her son does not really exist. It's just something her ex conjured up to try and get the pure hearted Grace to do something so dastardly he gets demon status. She is told that the only way she can break the spell is if she admits out loud that her son doesn't and never has really existed. Understandably, this is something that plays with Grace's emotions throughout much of the book. Anyway.....Caspian agrees to the pact with one condition. His payment is sex with Grace. In spite of a lot of rumbling from Grace, this is not a hardship since she is just as taken with him. I like that she was a strong woman and also a plus size woman. The chemistry between the two is fantastic. I love all the bad things Caspian rains down on Michael (Grace's ex); some of them were truly inspired. This is a book where the baddie got tons of punishment and very fitting punishment. The title refers to the fact that Michael tells Grace she has to lose the demon or else he will kill their son.
There are a lot of minor plots and secondary characters in this book but I found them all interesting. I liked the little side romances of Grace's supposedly dead grandmother - who is in fact the Baba Yaga - with Hades. I also liked that Petru & Katerina find love. When Petru was first introduced, I thought he would just be a little "lackey # 2" kind of character, but his story was actually very sweet.
This story was super-hot, very naughty, very funny, and had an enjoyable story and characters. I laughed so much while reading this book.
