A group of Australian teenagers return from a camping trip to find their country suddenly invaded. Cut off from their families and everything familiar, they must rely on their wits, courage, and each other to survive.
 
Across the first four books, the series follows their struggle to adapt to a world at war—balancing fear, friendship, and the harsh reality of growing up too fast. Each story builds on their efforts to stay alive and protect what they love while discovering how far ordinary people can go when everything changes. It’s an intense, emotional, and fast-paced journey about resilience, loyalty, and the loss of innocence.
