1987’s The Legacy of Heorot is the first volume in Larry Niven, Jerry Pournelle, and Steven Barnes’ Avalon series.
A century after being meticulously selected to establish Man’s first colony on an extrasolar planet, the settlers aboard the National Geographic Society’s starship Geographic establish a foothold on the Tau Ceti IV planet of Avalon. Prudently selecting an island for their settlement, they begin the task of transforming the island into an ecosystem in which humans can thrive.
Despite the unpleasant surprise that a century of hibernation has a cognitive cost apparently undetectable over shorter timespans, the settlers have thus far been successful in their bid to make Man’s Manifest Destiny IN SPAAACE a reality. Indeed, they’ve been so successful that ex-soldier turned security expert Cadmann Weyland seems superfluous to needs.
The settlers are overconfident. Cadmann is crucial to the colony’s survival — or he will be if he survives the calamity bearing down on the naïve colony.
