I liked the audiobook...

I enjoyed it quite a lot but it is basically a shallow beach read. And I don't normally read those sorts of books. I think this author is so popular because she hits a sweet spot where it's just good enough that it doesn't feel too repetitive, derivative and cheesy that can be typical of "beach reads," but her books are still juicy, fun and easy to read. I wouldn't recommend them as masterpieces but I would as something light and entertaining.
