I'd say 3,5 but that's impossible. I loved the imagery of this story, but because of the confusing timelines, that I had a hard time remembering, it was difficult to stay on track and engaged in the story. (which resulted in me not continuing reading for almost 2 months, and then finishing in 3 days after that... ) I think maybe I'll reread some day with a notepad for keeping track of the timelines ^^
