3.5 if I am being completely honest.
I liked the story and I really am anticipating the final story.
Knowing this author, there will probably be another novella in someone else's POV soon.
My only complaint would be some predictability. It doesn't take incredible intelligence to know who Gus really is to Ellie and who caused his mental breakdown, yet it is being kept such a secret. I guess to be a big surprise in the last book. There is a ton of action in this book and I did learn how to burn a man's face with non dairy creamer, which is always a plus.
