The Lost Man by Jane Harper

Two brothers meet at the border of their vast cattle properties under the unrelenting sun of outback Queensland. They are at the stockman’s grave, a landmark so old, no one can remember who is buried there. But today, the scant shadow it casts was the last hope for their middle brother, Cameron. The Bright family’s quiet existence is thrown into grief and anguish. Something had been troubling Cameron. Did he lose hope and walk to his death? Because if he didn’t, the isolation of the outback leaves few suspects…
Dark, suspenseful, and deeply atmospheric, The Lost Man is the highly anticipated next book from the bestselling and award-winning Jane Harper, author of The Dry and Force of Nature.
