Dune: The Battle of Corrin is a 2004 science fiction novel by Brian Herbert and Kevin J. Anderson, set in the fictional Dune universe created by Frank Herbert. It is the third book in the Legends of Dune prequel trilogy, which takes place over 10,000 years before the events of Frank Herbert's celebrated 1965 novel Dune. The series chronicles the fictional Butlerian Jihad, a crusade by the last free humans in the universe against the thinking machines, a violent and dominating force led by the sentient computer Omnius. The events of the novel take place a full century after the beginning of the Butlerian Jihad, and are divided into two parts, the first beginning in the year 108 B.G. (before Guild) and detailing a biological war waged by the thinking machines on the humans. The second part of the novel begins in 88 B.G. and covers the events after the Great Purge, leading up to the fateful Battle of Corrin. At the conclusion of the Legends of Dune series, several storylines started in the previous two novels lead to the political and social climate that is well established in Frank Herbert’s original Dune series. Dune: The Battle of Corrin rose to #9 on The New York Times Best Seller list in its second week of publication. Plot summary The machine evermind Omnius is continuing with his plans to eradicate all humans in the universe. After first being suggested by the traitor Yorek Thurr, an RNA retrovirus is designed by the captured Tlulaxa Rekur Van and the independent robot Erasmus. Omnius then launches capsules containing the retrovirus to infect the planets inhabited by the hapless humans. With a 43% direct-mortality rate, the virus succeeds in effectively crippling the League of Nobles, leaving them vulnerable to attack. It is discovered that consumption of the spice melange has the effect of both bolstering immunity to the retrovirus and stopping its progression in some of those already infected. Omnius, unaware that the virus has been effectively stopped, prepares for the second phase of its attack. Gathering the bulk of the machine armies stationed at the different synchronized planets, the evermind launches the massive fleet towards the League capital Salusa Secundus. After learning of the imminent destruction headed their way in the form of the machine fleet, Vorian Atreides formulates a plan whereby the humans can launch pulse-atomic attacks on all of the undefended Synchronized
