The book end very suddenly and you are left wondering about things. Do Kit and Cassie end up together or do Eb and Cassie get back together? Other questions remain unanswered as well. Book 2 picks up with a different set of characters in another location. Books 3 and 4 seem to stay with the characters from Book 2. TBH, I’ve only read Book 1 so the characters from Griffin may be in the other books. Not sure if I’m that interested in finding out though.
