Western Australia, 1896. The pearl-diving boat captained by Eliza Brigthwell's eccentric father returns after months at sea, without Eliza's father on it. Whispers from townsfolk point to mutiny or murder. Headstrong Eliza knows it's up to her to discover who, or what, is really responsible. As she searches for the truth, Eliza discovers that beneath the glamorous veneer of the pearling industry, lies a dark underbelly of sweltering, stinking decay. The sun-scorched streets of Bannin Bay, a place she once thought she knew so well, are teeming with corruption, prejudice, and blackmail.
