I'll be honest, sometimes it's a little on the fluffy/cheeky side for my taste. (EDITED TO ADD. Katy in the comments said that maybe I should try some of her books geared towards older YA. I have already put it at the top of my TBR!! Yay!) But there are times when it's exactly what I'm in the mood for. Of course, I haven't read all of her books so maybe they aren't all that way. Her newest looks very interesting and I'll be sure to check it out.
Last year I read ENDLESS SUMMER and really enjoyed it. Even did a review on the blog! :)
