I am writing this a long time after I read the book. Here is where Kurt Vonnegut discovers his outlandish style in which the science is largely made up, so it can barely be called science fiction. For example the "chrono-synclastic infundibulum" is more Hogwarts than Asimov.

What this book lacks is the lovely simplicity of language which Vonnegut mastered in his later works, to make his writing so absorbing even when he's bouncing all over space, time, emotion, perception and politics. But with a little more concentration, "The Sirens of Titan" still delivers that Vonnegut mind-warping dose of love and bemusement at the cosmos.
