3·5 - 3·75 stars. Not quite 4 stars, but very good. One of my favorite themes (marriage of convenience) and this one is kind of a MOC but with a twist.
There are a number of secondary characters which added to the story and their stories come to a nice conclusion.
In my opinion there were one or two threads left hanging hanging and that was incredibly frustrating since so many other things were satisfyingly wrapped up. It could be they are featured in another book. I'll have to look.. :)
