Tamora Pierce is a prolific and very unusual modern master of fantasy for young adults and the first such author to appear regularly on the New York Times bestseller lists. The four books making up The Protector of the Small are the 9th to 12th (of 15) novels set in Tortall, and follow the progress of Keladry of Mindelan from the first openly female page in more than a century to her attainment of Knighthood and introduction to war. The Notes cover Tamora Pierce's life and work; the world of Tortall (including the geography, cast, and neighbouring cultures); the strange menagerie of immortal creatures who may be friend or foe; the pantheon of interfering multicultural god/desse/s; knighthood; and the school series format that Pierce adapts. The well-illustrated Annotations <wbr>cover unusual words, ideas, and objects mentioned, real-world cultural, historical, and literary references, and the major thematic issues that develop throughout the quartet. First Test, Page, Squire, and Lady Knight are all covered on a chapter-by-chapter basis. The Essay considers The Protector of the Small as a revisioning of Song of the Lioness, the structure of the quartet, and the nature of Blayce and the killing devices. A Note on Fanfiction surveys the enormous Tortall archive of fanfic as a resource for readers of the quartet, and a Bibliography provides checklists both of Pierce's works and of writing about her. Tamora Pierce read the book in manuscript and has generously allowed her comments to be published, including new extracanonical facts about Jump, women in combat, the death magic that powers the killing devices, and much more.
