Books like We Need to Talk About Kevin?

Hi, my favorite book is We Need to Talk About Kevin. I'd really like a book like it, if possible. I'm in the middle of reading Baby Teeth right now because I found it online actually when I searched up my favorite book. I love books that actually make you think during and afterwards for a while. Not to be creepy but to be frank, I like to read about some real messed up stuff that sticks in your mind for a while after. Does anyone have any suggestions? Thank you so much! ❤️
