I really enjoyed this book. Yes it was predictable in places, like it was really obvious who the green witch was going to be. But it was a really nice easy ready that had me needing to read on in some bits. I loved the characters too, I loved how Cal was the level headed one, even if he was wrong, and him and Mae spent most the books snogging, but they were teenagers in love and I enjoyed seeing the reality of what that looks like, while the friends were just there rolling their eyes. My favourite character was Millie though. I loved her and her energy. It may have only been middle grade but I would definitely recommend it.
