Books like Vampire Diaries Collection

The Vampire Diaries was originally a trilogy, and it was only after some pressure from the fans that Smith wrote the 4th book. In some ways I think that she really should have left it at 3, because it's a wonderfully dark ending for a teen book and would have been much braver in my opinion. The 4th book is undoubtedly a lot weaker, with some truly shocking (and I don't mean in the good way) plot devices. Bonnie has taken over as the lead character in this book, and is unbelievably stupid for much of it.Do I still like it though after all these years? Yes. It's hardly an unbiased opinion given how much I loved these the first time round (having been the right age to be the target audience back when these were new books and not almost 20 years old...)Fans of the TV series who pick these up for the first time are in for a surprise because there are virtually no similarities between the two. I've been very pleasantly surprised by the TV show, mainly for its fantanstic plot and not just because it appears to be set in the town that ugly forgot.Now I'm moving on, with quite some excitement, to read the new trilogy ("The Return") for the first time. The first of which, 'Nightfall', was brought out before the TV series was aired but would have been written at a time when both were on the cards. The following two books (actually, the final one isn't published in the UK yet) were written and published after the rousing viewers responses to the TV show and I will be very interested to see how this affects Smith's writing and how true the characters will stay to her original early books.The first 4 books are aimed squarely at the teen market and are an excellent example of the genre that I still find enjoyable as an adult reader. I'm looking forward to the next 3....
