Megan: i started with the 3rd book Darkness everlasting and then skipped to the 6th book. I think it helps if you read them in order it might make some kind of sense for some. however they only have a slight relation through characters not exactly a continuing series. Different stories that only have relations between characters.
Manda: I like the books i have read all 6 in order within a 1 week period and i loved them and suggest that the series is a wonderful collection. i would hope that one day that these books will come to life on the big screen because it is something totally that will be better than harry potter and twilight and lord of the rings i believe this is the next big thing that should happen. i believe everyone should read in order to get the full story how the next book was lead to the next.
