Septimus Heap is a series of fantasy novels for children. Six novels, entitled Magyk, Flyte, Physik, Queste, Syren and Darke, have been published, the first (Magyk) in 2005 and the most recent (Darke) in 2011. A full colour supplement to the series, entitled The Magykal Papers, was published in June 2009. Sage recently confirmed on her blog that the title of the seventh book is to be Fyre.
The series follows the adventures of Septimus Heap who, as a seventh son of a seventh son, has extraordinary magical powers. After he becomes an apprentice to the arch ("ExtraOrdinary") wizard of the series, Marcia Overstrand, he must study for seven years and a day until his apprenticeship ends. In the first book, he is known as Young Army Expendable Boy 412, until his great-aunt, Zelda Zanuba Heap reveals his true identity. His adventures are placed in the context of the warmth and strength of his family, and developed alongside those of Jenna, his adoptive sister, who is heir to the throne of the Castle, the community where they live.
