Paul Park (born 1954) is an American science fiction author and fantasy author. He lives in Berkshire County, Massachusetts, with his wife and two children. He also teaches a Reading and Writing Science Fiction course at Williams College. He has also taught several times at the Clarion West Writing Workshop. Park appeared on the American science fiction scene in 1987 and quickly established himself as a writer of polished, if often grim, literary science fiction. His first work was the Starbridge Chronicles trilogy, set on a world with generations-long seasons much like Brian Aldiss' Helliconia trilogy. His critically acclaimed novels have since dealt with colonialism on alien worlds (Coelestis), Biblical (Three Marys) and theosophical (The Gospel of Corax) legends, a parallel world where magic works (A Princess of Roumania and its sequels, The Tourmaline, The White Tyger and The Hidden World), and other topics. He has published short stories in Omni Magazine, Interzone and other magazines.

Evangelisti earned his degree in Political Science in 1976 with a historical-political thesis. He was born in Bologna, where he currently lives; he spends some time each year in Puerto Escondido, Oaxaca, Mexico, where he owns a house. Until 1990 his career was mainly academic. He also worked for the Italian Ministero delle Finanze (Treasury Department). His first written works were historical essays, including five books and some forty articles. In 1993 his novel Nicolas Eymerich, inquisitore won the Urania Award, which was established by Urania, Italy’s main science fiction magazine, with the aim of discovering new talent in the field. Urania published other novels of the series in the following years: Le catene di Eymerich ("Eymerich’s Chains", 1995), Il corpo e il sangue di Eymerich ("Eymerich’s Body and Blood", 1996), Il mistero dell'inquisitore Eymerich ("Eymerich’s Mystery", 1996), Cherudek (1997), Picatrix, la scala per l'inferno ("Picatrix, the Stairway to Hell", 1998), Il castello di Eymerich ("Eymerich’s Castle", 2001), Mater terribilis (2002). Most of the last ones were however first published as hardcover. Nicolas Eymerich is a real historical character, member of the order of the Dominicans and inquisitor in the Spanish Inquisition. He was born in 1320 in Girona, Catalonia, and died in 1399. Evangelisti’s interpretation of his character is a cruel, ruthless, haughty, restless man, who acts mercilessly to protect the Catholic Church against perceived menaces of natural or supernatural origin. At the same time he shows an outstanding intelligence and a deep culture in his actions. In the novels of the series he investigates the mysterious phenomena of Medieval Europe, thus subtly influencing many of the historical events of that epoch; on many occasions the solution of the riddles comes up from stories which are narrated along with the main plot, normally set in the present and in the future. Evangelisti's atmospheres are normally dark, nightmarish, haunting. Another success of 1999, also translated in several languages, is the Magus trilogy, a romanticized biography of the famous Middle Ages prophecies writer Nostradamus. The three novels, Il presagio ("The Omen"), L’inganno ("The Deceit") and L'abisso ("The Abyss") sold 100,000 copies in Italy. Evangelisti's novels are greatly appreciated in France (where he won several literary awards), Spain, Germany and Portugal. He is currently the director of the Carmilla magazine. In the last years he has written some works which show his love for heavy metal music, namely the short stories collection Metallo urlante (referring to the French magazine Metal Hurlant) and the novels Black Flag and Antracite: they are set during the American Civil War and feature a new character, Pantera, a palero shaman. One of his latest novels, Noi saremo tutto ("We Shall Be All"), spans several decades of the last century, exploring the life of Eddie Florio, a gangster, against the background of the history of the trade unions and the workers' battles for civil rights. Mexico is the setting for his next two novels, Il collare di fuoco ("The Fire Collar"), which was published in November 2005 and Il collare spezzato ("The Broken Collar", October 2006). In 2007 La luce di Orione was released, the ninth title in the Eymerich series, followed in 2010 by Rex tremendae maiestatis. Tortuga, a novel about pirates of the Caribbean, was published in 2008.

Pat Cadigan is an American-born science fiction author, who broke through as a major writer as part of the cyberpunk movement. Her early novels and stories all shared a common theme, exploring the relationship between the human mind and technology. Her first novel, Mindplayers, introduced what became a common theme to all her works. Her stories blurred the line between reality and perception by making the human mind a real and explorable place. Her second novel, Synners, expanded upon the same theme, and featured a future where direct access to the mind via technology was in fact possible. She has won a number of awards, including the prestigious Arthur C. Clarke Award twice,in 1992, and 1995 for her novels Synners and Fools. She currently lives in London, England with her family.
