This is actually my second attempt at reading an Evanovich romance and it will be my last. There is so much I didn't like about this story. It is written only from Chris' POV which bothers me when reading romances. The addition of Aunt Edna is clearly meant for humor, but fell far short of that. Instead, the character seemed fake and forced into it. Chris and Ken are in love with each other about 50 or so pages in and pretty much coast along until she finds out his Big Secret. There was practially no character development in this book, especially with Ken. It was just bland, boring, and a waste of my time. I could've been reading a good book!
However, I can see people liking it. Evanovich has a strong fan base who appear to not notice what seems to me to be a complete lack of improvement in her writing and storytelling abilities. Those two reasons are why I stopped reading the Plum series at book nine. If you liked her other romances, I'm sure this is just more of the same and you'll probably enjoy it. Same goes if you don't like her other ones. Don't bother with this one, it doesn't get better.
