I gave this book more than 1 try but found the characterization very inconsistent. On introspection, the heroine kept alluding that she was going to resist getting intimately involved with her husband of convenience but was then getting naked in front of him, or performing sexual favors for him. I found the hero quite insensitive and I couldn't see these two together.
The plot seemed rather contrived with regard to the heroine's twin disappearing with his wife & the lack of concern or "grieving" on the part of the family didn't ring true. The lack of involvement on the part of the heroine's mother was a glaring hole in the plot.
I read approximately 30% of this story.
