Vonnegut's take on end of the world which is part accident and part lack of administration. The creator of a weapon that pummels the landmass designs it because, science. The accidental nature of science, happenstances and religious undertakings make up Cat's cradle. 
 On a side note - while reading, Vonnegut sounds easy, clear and "yeah, I get it" but when trying to review, I can't figure out where to start let alone what I want to convey. Thus sticking to a vague three liner and a four star rating.
