She is the author of a children’s book entitled Fröken Selma! (‘Miss Selma!’, 2013) and a book about the restauration of a worker’s house at Mårbacka, Arbetarbostaden på Selma Lagerlöfs Mårbacka (‘The Worker’s House at Selma Lagerlöf’s Mårbacka’, 2014). She is a member of Selma Lagerlöf-sällskapet (the Selma Lagerlöf Society).
