The Seven Deaths of Evelyn Hardcastle

First of all, it has a couple of red flags:
1. Unnecessary mention of sexual abuse, that doesn't play a big role in the story and that is not properly addressed afterward
2. Potentially triggering description of a plus-sized character

That said, this was a book that I wasn't expecting to enjoy so much! It captures you (if you enjoy very descriptive and atmospheric writing) and doesn't let you go till the very end. The mystery becomes almost an obsession while you spiral down together with our main protagonist.
I believe that it can be classified as a murder mystery in a secluded location and really makes you feel like there is no escape.
