In the beginning, the story is scary, but in the Utah chapters it becomes as funny as it was scary. Spoiler: The story in a nutshell A terrorist group led by someone called John wants to build a giant machine for unknown purposes in the middle of the USA, and the only thing that stops them from that is an absence of a cement mixer truck. They figure out that the best way to get it is to steal it from a construction site on the other side of the country, then blow up the site, imitate the dna and fingerprints of a local lumberjack and put them there. There is a major flaw in they plans, though: the lumberjack happens to personally know John, their leader.
