Heaven and Hell (Heaven and Hell #1) by Kristen Ashley

Kia Clementine is taking a long needed vacation in Europe. She recently became widowed. She is not sad her husband is dead. She married young and was abused by her husband for years. She never let her family interfere  He always told her she was worthless and he can hurt her family too. 
She is shocked when she goes for breakfast and Sampson Cooper is sitting next to her. He is a very famous ex-football star and also was is some type of covert operation. They sit together and spend time together. This blooms into another date.
But not everything is easy when Sam learns that Kia's ex has
placed a hit on Kia's life. That is why we see a couple of cameos of Lee Nightingale, sigh!
This couple has some issues to deal with. Both of them have been hurt. They both learned to open up to each other.
