I'm pretty sure there isn't one already. I read Slaughterhouse 5, The Sirens of Titan, and Cat's Cradle. The thing I've noticed is there is connections between each book, such as a reference to Rumfoord in Cat's Cradle, and the alien from Tramalfadore in both Slaughterhouse 5 and The Sirens of Titan. Slaughterhouse 5 is my favorite so far. So it goes.
