I enjoyed this book and the characters, but felt as though there were so many "new" ideas and concepts that plot holes might have been there and I didn't even notice. I am ok with revealing a character's backstory slowly, but with some characters (such as Finn) I didn't even understand what they were doing in the story. With the character of Katie, I didn't understand her at all until it was mentioned later that she was only 16. With Holly, it was unclear that she wasn't Aggie's daughter until much later in the book. I will read the sequels to this story and hope that the author starts to realize what to reveal and what to save for later.
