The horror elements here will give you a pleasant thrill, but nothing too hard core. So if you're wondering whether you'd handle it, you'll probably be okay.
I've mostly read older horror stories before, and I appreciate the newer perspective here. (The book is published in 2019.) The heroine reacts as a modern person - aware of the horror genre and not willing to take anything supernatural at face value - might. That, combined with plenty of humor, make for an amusing read.
On the other hand, I wish the author would cut down on the humor and witty commentary in the latter parts of the book, when the going gets tough. There it just takes you out of it. Yes, we get it, you realize how ridiculous this would sound if you told anyone. And that you can make jokes. Pls focus on the monster currently eating you, instead.
