The Seven Deaths of Evelyn Hardcastle

Somewhere between 3.5 and 4, to be specific.

Definitely the most creative, original and intricate plot I've read in a long time. If you are a fan of some detective work and mind puzzles, you'll enjoy this. I definitely found myself mulling over what seems to be the main thesis of this book- I won't state it here since, spoilers, but it is interesting to ponder over- though ultimately I do not agree. The setting was definitely an interesting way to present the themes this book covers.
