The Heiress Effect
Bloody brilliant.
I was just going to let my review be that, but I thought I'd better explain why I felt that way. Every book (or novella) that I have read by Courtney Milan I have enjoyed and this was no different. She writes flawed characters that are so compelling that you can't help but fall in love with them.
If you've read the previous books in the series you'll know that Oliver is the Duke of Clermont's half-brother. He has spent his life dealing with the fact that he the bastard son of the previous Duke. In this book he meets Jane who is an eccentric heiress. As he fights for a place of power and she fights to protect her sister they will find themselves growing close, which neither of them wants.
This was my favorite book of the series so far. I was so hooked in the story and really loved Oliver and Jane. I felt like I flew right through this and was mad when I got to the end because I never wanted it to end. I would definitely recommend this to fans of the previous books in the series. I plan on reading the next book in the series (I purchased it when I was about 20% of the way through this one). I am also looking forward to reading some of Milan's other series and stand-alone books.
