Looking for books with a very casual writing style

Hello! I would like to get back into reading. The most recent books that I've enjoyed were Fight Club by Chuck Palanuik, Slaughterhouse Five by Kurt Vonnegut, and my favorite of all, White Tiger by Avarind Adiga. These are all books that have more laid back tones. I think these are more enjoyable because I haven't done much reading in my adult life, and more theatrical books felt a little challenging for me to comprehend what's going on. It doesn't have to be a huge adventure, it can just be a fun slice of life. Thank you!
