Tomorrow, when the war began

The narrative arc of the initial conflict is established in this volume, but it serves as the opening entry of a seven-book series that continues the characters' journey and the broader war effort.

The novel was adapted into a feature film released in 2010 and later served as the basis for a six-part television miniseries produced in 2016.

The identity of the invading power is intentionally left unspecified throughout the original novel, as the author focused on the teenagers' survival and internal experiences rather than geopolitical specifics.
