Unputdownable Page Turner- but not Thriller, Sci-Fi or Fantasy!

All I read is thriller, so I’m looking to take a break- but I love how thrillers grip me. I love weird, triggery stuff. Some non-thriller favs: My Dark Vanessa, All the Ugly and Wonderful Things; thriller favs: Gone Girl, Little Secrets. Thank you in advance!! by MyYummyLatte
