In 1999 she wrote and illustrated a children's book about the American astronaut Michael Collins titled The Man Who Went to the Far Side of the Moon: The Story of Apollo 11 Astronaut Michael Collins. In the mid-1990s she became interested in S. A. Andrée's Arctic Balloon Expedition of 1897 and tried to find out what happened to the expedition members. This research resulted in the book The Expedition, published in English by Head of Zeus in 2014, and for which she was awarded The August Prize in 2013.
