The Bartimaeus Sequence is a series of children's novels of alternate history, fantasy and magic. It was written by British writer Jonathan Stroud and consists of a trilogy published from 2003 to 2005 and a prequel novel published in 2010. The eponymous character, Bartimaeus, is a five-thousand-year-old boisterous djinni. The story follows the career of a teenage magician Nathaniel and Bartimaeus, whom he has summoned and nominally controls, through the alternative history of the peak of London's domination as a magical oligarchy.
