First of all, I'm a huge fan of L.J.Smith and The Vampire Diaries show. I don't like Stefan that much but I thought it would be fair enough to hear the story from his point of view =).
The first two books were great, really enjoyable, the only reason I gave this sequel 4 stars because there were some really boring parts in it, in which he would keep reminding us of what happened in the previous volumes, it was really boring. After Damon got into the story, things got better of course.
Overall, I really enjoyed it, especially at the end, it was worth reading and I would definitely read it again =).
