Maureen Mollie Hunter McIlwraith writes under the name Mollie Hunter. Mollie Hunter is one of the most popular and influential twentieth-century Scottish writers of fiction for children and young adults. Her work, which includes fantasy, historical fiction, and realism, has been widely praised and has won many awards and honors, such as the Carnegie Medal, the Phoenix Award, a Boston Globe - Horn Book Honor Award, and the Scottish Arts Council Award.

There has also been great interest in Hunter's views about writing fiction, and she has published two collections of essays and speeches on the subject. Hunter's portrait hangs in the Scottish National Portrait Gallery, and her papers and manuscripts are preserved in the Scottish National Library.

Her books have been as popular in the United States as in the United Kingdom, and most are still in print. Critic Peter Hollindale has gone so far as to assert that Hunter "is by general consent Scotland's most distinguished modern children's writer."
