To Hell with Love had a very interesting premise, Hades the god of the underworld is out to find a loving companion to end the dark loneliness of his immortal existence. Interior designer Kate draws Hades notice when she responds to the question of who would be the perfect man to date and replies that it would be the devil but it would take more than a couple of dates before she'd be willing to give up her soul. But of course Hades who makes his appearance a year later as rich and handsome Owen doesn't do souls, and anyway what he really wants is Kate's heart for all eternity.
Though the premise was great the execution is not typical of your standard romance novel, more time was spent developing Kate and her family than the relationship between Kate and Owen, making the romance between the two not developed enough in the first two thirds of the book to give it a real intensity. In fact Kate spends way too much time dreaming of being with Owen and waiting for his calls and not enough time in his company. When they actually do spend time together, Owen is so omnipotent that their conversations have a very odd feel. Also since Owen does grand gestures but doesn't do a great deal of acting on the emotion that Kate sees in his eyes -- while he also keeps fending off Kate's blatant seduction -- it felt at times that all the love between them was in Kate's head.
As strange as it seems with everything I've said so far, the book did redeem itself in the end. So while I can understand why some reviewers couldn't get past all this, somehow in the last third of the book once Kate and Owen got to the crisis point in their relationship, where he reveals his true identity and wants her to make the choice of loving him at the cost of giving up her life and her family, I really started to finally connect to these two. And since this crisis point also coincided with a family crisis for Kate, the final development of her character and the clarity that brings really added depth to the story. Add to that Owen finally learning the selflessness of love and sacrificing when there was no compromise along with the bittersweetness of his sacrifice and I ended up liking the book. But I have to admit that I did cheat and read the other reviews, so I was prepared when the author didn't succumb and give us the easy typical romance novel happily ever after.
If you don't mind unconventional HEAs and like the mythological tie-in of To Hell with Love, you might want to consider checking out P.C. Cast's books. She has several goddess related works that have a similar bittersweetness if you are looking for something a little out of the mainstream romance norm.
