Cahill Files: The 39 Clues

The Cahill family sits at the centre of The 39 Clues, and this companion volume turns its attention to the records, missions and rivalries that the main series only glances at. Clifford Riley builds the book around files and case material rather than a single continuous plot, so young readers move through episodes of intrigue, coded history and family manoeuvring. It works as an extension of the series rather than a starting point, rewarding anyone who already knows the branches and their long quarrel. Inside the book: • A companion title to the bestselling 39 Clues series, written by Clifford Riley • Built around dossier-style material on the Cahill branches and their operations • Short, fast episodes suited to readers around ages eight to twelve • Published by Scholastic in English Middle-grade readers who like codes, spycraft and long-running family rivalries are the natural audience, and the Scholastic edition can be ordered from Boipoka.
