It was good but flawed. The author threw the whole subplot of the h's mother in the story as a red herring, and the implication that the h's late father wasn't her bio dad is just dropped. The h says she wants to know more but never pursues it.
Of course, with all the accidents and murder attempts, hat is a bit understandable. Still, I guessed from the start who the real culprit was and of course, she suspects the H for a time since they had a whirlwind romance/marriage, but there were so many clues she should have realized long before she did who was really responsible.
