I liked Mac and Isabella so much in The Madness of Lord Ian Mackenzie that I remember pre-ordering this book, staying up until it downloaded onto my Nook at like 12:15 AM and then reading the whole thing in a few hours. One of my absolute favorite tropes in romance is a story in which the characters marry either at the beginning or shortly after the book begins. One of the tropes I actually like less is marriages in which there have been separations and now they're reuniting. This is generally because when a married couple separates, particularly in this time period, it's usually through the bad behavior of one of them. I actually hate unfaithful couples -- it's so hard for me to look past it. I know, it's prudish of me, but I know what I like.
That was not the issue here, thankfully. Mac and Isabella separated three years prior to the beginning of this story because Mac was too much--he drank too much, he partied too much, and he just wasn't really emotionally healthfully enough to be in a marriage, and I think Isabella was just too young to really know how to do anything about it until it reached the breaking point.
I loved watching them find their way back to one another and deal with life throughout the book. There is a decent amount of plot in this book with a wide supporting cast, but it never feels like overkill. It just feels like Isabella and Mac are getting to know each other again, realizing who they are underneath it all. I loved this book so much -- almost more than the first book though that's pretty difficult to say.
