This one seemed a lot more focused on the romance then the other books in this series. Maybe I'm remembering wrong, since it's been a while since I've read the others, but this one didn't really have a plot beyond the romance and their siblings getting married. That isn't really a complaint, but it seemed a little odd to me. I liked Sidney and Vaughn together, but it took them along time to get their act together! I expected them to meet at the wedding, so having them met before was a little misleading.
I expected to have a lot to say about this one, since I read it in less then a day and I haven't been reading that much lately (I burnt myself out). I can't really come up with that much to say, I think I've lost my ability to review books. Maybe not, but I can't think of anything else to say for this one.
