''Zodiac'' is an eco-thriller written by Creator/NealStephenson, published in 1988. It tells the story of an environmentalist, Sangamon Taylor, uncovering a conspiracy involving industrialist polluters in Boston Harbor. The title refers to the brand of inflatable motor boats Sangamon uses to travel across the Harbor, shortcutting Boston's frequent traffic gridlock. [[note]]the novel was written before the completion of the Big Dig, a major civil engineering project that created cross-city tunnels to help alleviate chronic traffic problems.[[/note]]

Sangamon Taylor is known as an Eco-terrorist by his opponents, and the "Granola James Bond," by the local student papers. He comes across as both, with a dash of HunterSThompson thrown in for good measure. Although he looks down on hippy tree-huggers, he fights against polluters using a variety of legal and illegal methods.

Much of the plot concerns Boston's Spectacle Island, which at the time of publication was composed entirely of garbage. In the story, it is frequented by drugged-out and reputedly Satanic groupies of the "two-umlaut" heavy metal music band, P÷yzen B÷yzen, who are too intoxicated with angel dust to realize that Sangamon is searching for toxic ''PCB's'' dumped on the island, not the drug ''PCP'', which they sell. HilarityEnsues.

!! This work provides examples of:
* CorruptCorporateExecutive: Pleshy in particular, most of Basco in general.
* EstablishingCharacterMoment: On his way to work, Sangamon forces his bicycle into heavy traffic. When a driver yells at him, he unleashes a crushing ClusterFBomb.
* GranolaGirl: Most of Sangamon's co-workers.
* HeavyMetalUmlaut: P÷yzen B÷yzen
* InsuranceFraud: Boone has become an insurance fraud ''meme'' -- whalers who want to get out of the business sink their own ships and blame it on him to get an insurance payout.
* IntrepidReporter: Rebecca.
* {{Jerkass}}: WordOfGod is that Stephenson designed Sangamon to come across as an obnoxious asshole.
* PunkPunk: Zodiac features many character archetypes, such as an antisocial renegade fighting megacorporations and their evil schemes. In addition, there is a focus on technology and how it affects society [[spoiler: such as the genetically engineered bacteria that can clean PCB spills, but also could be used to make PCB as well.]]
* ScifiGhetto: Averted by the author. Stephenson has the book listed as Science Fiction, even though it really doesn't have any speculative elements to it.
* ShroudedInMyth: Boone.
* SkeletonsInTheCoatCloset: Sangamon's toxic-waste-spattered tennis shoes are a modern-day equivalent.
