In this concluding work, Vonnegut uses the premise of a timequake (or repetition of actions) in which there is no free will. Vonnegut uses the idea of determinism as in many of his previous works (Slaughter House Five) to assert that persons really have no free will. Kilgore Trout serves again as the main character.
In the conclusion of this book, Vonnegut meets other authors for a celebration to recognize Trout as a hero. With this recognition, Trout alludes to being sleepy. UltimatelyVonnegut uses Trout thus to express his stepping down from writing novels and his increasing closeness to death.
