This was pretty good, and both the H and h were likeable characters (despite a few flaws), while everyone else, with the exception of the H's mother, sure left a lot to be desired!
The OM was avaricious and unscrupulous, an "end justifies the means' person who cared more about money than he did the h. She was well rid of him!
The H's niece was a rebellious, trouble-making teenager, but she could be excused, considering the parents she had, and she redeems herself later.
The rest are only talked about, never seen, but they still make an impact. The h's cousin, who she hero-worshipped, sure had feet of clay, and was hardly worth anyone risking their life for! The H's brother was weak and lacked a backbone, taking a drastic solution to his troubles without a thought to how it might affect his daughter. The H's sister-in-law was self-centered and irresponsible (as well as a cheater), and she had no qualms about dumping her parental responsibilities onto the H. The h's parents had an "on again off again" marriage and were both on the silly side.
The OW only makes a brief appearance so you can't judge her at all.
As for the H and h, they both start off misunderstanding each other terribly, and each has a tough time overcoming their prejudice, despite evidence to the contrary. It takes time for them to finally get on track (a bit too long, if you ask me), and a lot of things have to be cleared up first, which takes away from time they could have been together as a couple.
Still, it's worth checking out.
