Some disasters are ordered in advance.
Before dawn off Darwin, Owen Rourke hauls a marine electrician out of a burning boat. The man dies hours later, leaving a warning that refuses to fit the official account.
A former SASR soldier, Rourke now earns his living aboard the salvage boat Bellwether. He has no appetite for another fight. But insurance investigator Mara Venn has questions of her own, and the records point towards more than a single failed system.
From Darwin to Singapore and the shipyards of Batam, they uncover falsified tests, recycled equipment and a business built around emergencies. At its centre is a company promising to protect the infrastructure Australia cannot afford to lose.
Following the money is dangerous. Proving what it buys may be worse. As the pressure reaches his family and the threat turns towards home, Rourke has to decide how much of his new life he can risk to stop the next disaster.
The Sovereign Line is a complete standalone thriller featuring Owen Rourke: a story of maritime action, contested loyalties and the quiet surrender of control. For readers who like their conspiracies credible, their heroes fallible and their stakes national.
