Short Book To Make My Reading Goal That Won’t Make Me Sad (again)

I started The Kite Runner a little while ago and got up to that part. It was hard to continue.

I was busy with exams but I can dedicate a good amount of time reading so short is up to you. I take my Kindle everywhere, I’m open to audiobooks, and I’m a fast reader.

Can you suggest a short feel-good book?
