Like I know I'm going to the past? A book of herbal remedies. If this is a book for enjoyment sake then I would say maybe The Way of Kings by Brandon Sanderson, Cultish by Amanda Montell, or Hood Feminism by Mikki Kendall. Those are just three that came to mind because I enjoyed them a lot. I also love Fight Club but people always wanna dog on it. It was the first book I'd ever read with a legit plot twist. I've always loved reading but I didn't know how exciting reading could be until then.
