Willy Ustad (born 16 May 1946 in Trondheim) is a Norwegian novelist. Early life Ustad grew up in a heavily forested part of Trøndelag. He was an army employee until he was past 30, and later a metalworker and active union member. Health problems forced him to stop working in the factory, and he started writing full-time. Writer He is a popular novelist, publishing close to 80 titles published 1989 and 2015. He is a member of the Norwegian Authors' Union. The Union has a literary council. Members must have at least two works judged to have literary value. Of several series, his most popular is Fire søsken (Four Brothers and Sisters) (42 books). Others are Opprør (Uprising) (about 1960s type radicalism, 7 books) and Vokterne (The Guardians), an X-files-like science fiction series of 6 for young adults. Style Settings His books depend heavily on his background, as well as extensive research. They are often placed in Trøndelag, both in the largest city Trondheim, in smaller industrial cities, the countryside and unpopulated forests and mountain landscapes. They may continue into the large forests of Sweden across the border, or occasionally further, including the Soviet Union, Japan and the United States. Characters Military and security personnel, industrial workers and working women - often unwed mothers - as well as small farmers and city criminals are among those who populate his books. Most of them have female heroes. Themes His tales mix historical and social realism with the fantastic in the form of ghost stories, local legends and science fiction. Many have spy themes come from the Cold War. Some are realistic crime stories, some fantasies, several are airplane thrillers (among them a book about the U-2 Crisis of 1960), some are documentary novels about historical themes, while one or two are erotic novels. Linkages Most of his books link with each other through common characters, settings and themes. A novel about the Norwegian prewar detective hero Knut Gribb describes the building of a factory that is important later in Fire Søsken. Characters from that series participate in the series Vokterne. A priest described in a historical novel about the Black Death makes an appearance as a ghost several hundred years later in a Fire søsken novel. In one sense, they might be regarded as parts of a still expanding mega-novel. Legends One of his early non-series books, Ulvetid (A Time of
