Everything you need to understand or teach The Lost Man by Jane Harper.
This mystery novel from New York Times bestseller Jane Harper is the story of three brothers from Queensland. The middle brother, Cameron, is found dead at the stockman's grave - an isolated stone in the middle of the outback which happens to be the subject of his award winning painting. There are no clues and no suspects, and after-all, the cruel summer's heat mixed with the constant isolation that comes with living in the Australian outback is enough to drive anyone mad. But Cameron had been acting peculiar leading up to the day of his death, and neither a murder, nor a suicide goes unquestioned - especially for a man with years of outback experience and a car stocked with a weeks supply of food and water.
