On a routine surveillance flight east of the Australian coast, Captain Lauren Bennett's crew pick up a mayday call. A yacht is under fire. For the international smugglers operating below the radar of the navy and Border Watch, sinking a pleasure craft is just part of their day's work. Lauren has other ideas. As she pursues the men into the isolated country of Cape York, she'll need all the help she can get. That will mean joining forces with the cynical navy officer Callam Granger, who's already shown his contempt for her. What will it take to convince him she's right this time? Can they put aside their old animosities to outwit, outrun and ultimately out-fly the traffickers? Or will another death shatter Lauren's life completely?
