Central Otago's searing summer has been long and brutal. And yet somehow the sheep and smaller creatures on Stonefields Station have survived. That's until Garth Fischer arrives, along with his gun and plans to change things in a big way. Then three youngsters — Tamsin, the farmer's daughter, and city-kids Dylan and Nimish — make an important discovery in Skink Gully. A find they must now protect. But Fischer will do anything to get his way, even if that means destroying the gully and all that live there.
