The Martian Chronicles, Dune, Ender's Game, The White Mountains, Hitchhiker's Guide to the Galaxy, & 2001, a Space Odyssey are all books I enjoyed and prolly good places to start, depending on your preferences. lmk if you want a synopsis of any
edit: Slaughterhouse Five is a pretty shaky way to start reading sci-fi. I would barely consider it sci-fi or even a novel as much as an art for its own sake. One thing is does share with a lot of sci-fi though is an otherwordly social commentary. If you liked that, you might like sci-fi a lot.
