The Alchemist and Song of Achilles are some popular books that I thought were mediocre. Probably not the worst book I've ever read though.
That probably goes to Sean Hannity's Conservative Victory that my grandma gave me when I was 12.
True slop. Fuck Sean Hannity.
I didn't read the Zahir but I felt like The Alchemist was a shallow Siddhartha-wannabe when I read it. I couldn't help but think it was trying too hard to be profound
