This series has a really good cast of characters. That's probably the thing about it that I love the most. They're all unique and they're all flawed and the relationship dynamics are great. You really get caught up in their life, their drama, and their romances. 
 I also love the unique world that Mead has created. I love that every book in the series is just as entertaining as the last one. I love the excitement and the fact that there's never a dull moment because the pacing is fantastic. 
 Basically, I just love this series :)
