Short Addictive Books

Hello!
I have to read 4 books to reach my goal I set for myself last year! I’ve really enjoyed reading lots of different kind of books over the year, mystery, fantasy, sci-fi, literary fiction. I’m looking for some book recommendations to get me to my goal! They have to be short, as I’m busy with college and don’t have a huge amount of time this month 🙂 let me know if there are any short punchy novels you’ve enjoyed recently (I’m also easy with genre, just nothing to tragic at the moment please) 🎉🎉
Thank you 🙂
