A Killing Frost by John Marsden

A tight-knit group of teenage resistance fighters in occupied rural Australia struggle to keep their campaign alive through a harsh winter, mounting sabotage and guerrilla raids while facing increasing danger, personal loss, and moral uncertainty; as operations grow bolder and the costs of resistance climb, the protagonist must reckon with leadership, loyalty and the blurred line between survival and becoming what they are fighting against.
