Wizard At Large by Terry Brooks is the third novel of the Magic Kingdom of Landover series, following The Black Unicorn. Written in 1988, the plot has Abernathy accidentally transported to Earth by one of Questor's ill-conceived spells, while a demonic imp is unleashed upon the kingdom of Landover. It was the last of a trilogy of annual Landover novels until The Tangle Box was published six years later. The book was re-released as part of a Landover omnibus in 2009.
