I intially read Vampire Academy a few years ago when one of my roommates had the first four books. I remember enjoying it but at the time I wasn't reading a lot and did not have much to compare it to. Now I am rereading the series and plan to finish it.
Going back into it I rememebered the basic plot and characters but not many specifics. I did find that I really enjoyed the book more than I initially remembered and look forward to reading through (and finishing) the series.
I am also excited for the movie next year. I think the marketing direction is a bit inaccurate but the articles I've seen from people who have seen actual footage is pretty positive.
