Let's talk about Diana's sister, Elizabeth. All Elizabeth did was puke throughout the entire novel (hello, morning sickness!). She was so faded in the story, letting life roll on by but I was truly surprised by her ending (and Diana's, too).
Carolina's story was fine but I'm not a whole-hearted fan of hers. I still think she's going to end up with Tristan, since she's also a major liar.
The Palm Beach setting was a nice change and kept the action rolling along. I'll definitely read all the books in this series because they're freakin' addictive. Also, all the covers in the series are amazing.
