The book "Tomorrow When the War Began" by John Marsden is about a group of teenagers who go on a camping trip and return home to find that their country has been invaded. They become guerilla fighters to rescue their families and fight for their survival. Throughout the story, the characters are forced to do things they never imagined, like killing others, in order to survive in the war. One character, Ellie, sets a garden on fire and kills three soldiers who were chasing her friends in order to save themselves. Surviving the war requires the characters to do extreme acts, even if they are bad, to stay alive against the invading forces.
