I also wasn't expecting all the sex in this book. Not that it was a bad thing, as some of the sex scenes furthered the plot tremendously, just unexpected for what I thought (and I don't know why I thought this) was a YA book.
Anyway, this is one of my favorite kinds of books - a witch coming into her powers and being more powerful than anyone thought possible. YAY! And throw in a hunky bodyguard that doesn't mind a strong woman? Bonus! Oh, and it's also a period novel, so if you enjoy castles, politics, and royal lineage, this is the book for you.
It's fluffy in a good way and is an enjoyable read.
