Well I have to admit the hero was a bit of an unlikeable and judgemental jerk at first when it came to women, having been burned by his ex a few years ago who was money minded he was quite adept at playing the field and his brother's past assistants had hit on him so he was not happy that the heroine would be taking residence at their ranch to help his brother out with his book. I liked how the heroine put him straight many time, even she had been burned but had thrown herself in her studies and had done so without family support. So, when the hero suddenly overcomes all opposition to their involvement and wants her to reciprocate she isn't that conducive to it because she doesn't want to be part of his long line of women.
I liked how she was cautious and wary of any involvement with him and that she kind of confused the hell out of him. The hero's journey from a jerk to a better person was well done. There were minor quibbles I had like I found some of the heroine's actions stupid, like when the hero warned her that someone could be involved in the cattle rustling she was too trusting of that person even though she didn't know him that well. I mean trusting some guy you don't know that well over the man you love, not very nice. I mean she did turn out to be right but that is not the point but besides this I liked the book, the hate to the lust to the love.
