Planet of the Damned is a 1962 science fiction novel by American writer Harry Harrison. It was serialised in 1961 under the title Sense of Obligation and published under that name in 1967. It was nominated for the Hugo Award. Planet of the Damned follows Brion Brandd, a character who lives on the planet Anvhar, which, due to an elliptical orbit, experiences a year with a long cold winter and a short hot summer, to which the population have become adapted. To avoid social problems during the winter period, Anvhar has initiated a planet-wide series of mental and physical games called the Twenties. The novel starts with Brandd winning the Twenties. As he recovers from the games, Brandd meets Ihjel, a previous winner of the Twenties, who asks him to join a mission on the desert planet of Dis. The ruling class of Dis, the magter, have threatened to transport cobalt bombs onto a neighbouring planet if they refuse to surrender. As a result, the planet is being blockaded and under threat of a pre-emptive nuclear strike. In the novel, Brandd travels to Dis with Ihjel and a scientist from Earth called Lea, but on arrival the trio are attacked and Ihjel is killed. After encounters with the local population and other humans, Brandd starts to put together the reason for the magter's seemingly suicidal aggression. Brandd learns that most life on Dis survives the extremes of the planet by using symbiosis. The magter, though, have been infected by a parasite that destroys the higher functions of their brains. Eventually Brandd locates the cobalt bombs and disables the transmission mechanism, allowing him to return home. (wikipedia.org) About the author: Harry Max Harrison (born Henry Maxwell Dempsey; March 12, 1925 - August 15, 2012) was an American science fiction author, known mostly for his character The Stainless Steel Rat and for his novel Make Room! Make Room! (1966). The latter was the rough basis for the motion picture Soylent Green (1973). Long resident in both Ireland and the United Kingdom, Harrison was involved in the foundation of the Irish Science Fiction Association, and was, with Brian Aldiss, co-president of the Birmingham Science Fiction Group. Aldiss called him "a constant peer and great family friend". His friend Michael Carroll said of Harrison's work: "Imagine Pirates of the Caribbean or Raiders of the Lost Ark, and picture them as science-fiction novels. They're rip-roaring adventures, but they're stories with a lot of heart." Novelist Christopher Priest wrote in an obituary: Harrison was an extremely popular figure in the SF world, renowned for being amiable, outspoken and endlessly amusing. His quickfire, machine-gun delivery of words was a delight to hear, and a reward to unravel: he was funny and self-aware, he enjoyed reporting the follies of others, he distrusted generals, prime ministers and tax officials with sardonic and cruel wit, and above all he made plain his acute intelligence and astonishing range of moral, ethical and literary sensibilities.
