They were an unlikely pairing but just what the other really needed. He made her feel desired, beautiful, and strong. She made him feel needed, accepted, and cared for. 

A miracle--that's what this was. Astounding that her life should've intersected with his here, of all lonely places on this gigantic planet. That she'd had reason to need him, and to linger. That she wanted him, and he her, that he'd revealed himself as he had, and that she'd liked who he was. That for once, both halves of his feelings for women--the desire for companionship and the desire to slake his strange appetites--were embodied in one person. 

I liked them together. Their relationship built slowly, but became a deep, intense connection. But they had obstacles in their way. They lived in separate countries and had separate lives. And Rob's past continued to intrude on the present. I admit that the book started a bit slow even though it was intriguing and about midway when some of his dark secret desires were revealed, I felt that they kind of overpowered their romantic connection especially in the sex scenes. Although I see that it was necessary for him to truly open up and feel accepted. It just seemed a little much detail for the story.  But it also tied in with his other secret shame, so it was all intermingled and all had a huge effect on his previous behavior and self imposed seclusion. But I am used to more dominant men so it was a little hard to get on board with.
