Wolves) describes the flight of a slave girl during the late Viking age, into a forest where she joins a group of wolves. This is based on a local legend. On her way she passes through a large battle, and she meets the hulder, a supernatural woman that belongs to the subteranians still feared in remote parts of Norway. The novel was sold in the museum shop at Stiklestad in Trøndelag, that commemorates the Battle of Stiklestad in 1030, where Olaf II of Norway fell. He was later sainted as St. Olav, Norway's patron saint, with a wide cult around the North Sea in catholic times. Ustad has written a couple of non-fiction books about flying saucers. Social issues Social issues have been the driving force behind many of Ustad's books. Tyskertøs The Fire Søsken series started with the novel Tyskertøs (a derogatory word about girls who went with Germans during the Nazi occupation), about a girl who has an out-of-wedlock baby with a German soldier on the day the war ends in 1945. It tells the story about the persecution of these women during the liberation days, which has been a taboo theme in Norway. The book set a record as the up to then best-selling first novel in a series, and was made into a radio play for the official Norwegian channel NRK. The main protagonist in Tyskertøs, Lena Karlsbu and her very diverse brothers and sisters become the heroes (and sometimes antiheroes) of the rest of the series. They became a vehicle that allowed Ustad to excavate several taboo real-life stories in later books. As he continued exploring this in the series, he received death threats from people who thought he was writing about abuse they had been involved in during the 1940s.
