Nobody leaves Osiris. Osiris is a lost city. She has lost the world and world has lost her... Rising high above the frigid waters, the ocean city of Osiris has been cut off from the land since the Great Storm fifty years ago. Most believe that Osiris is the last city on Earth, while others cling to the idea that life still survives somewhere beyond the merciless seas. But for all its inhabitants, Citizens and refugees alike, Osiris is the entire world, and it is a world divided. Adelaide is the black-sheep granddaughter of the city's Architect. A jaded socialite and family miscreant, she wants little to do with her powerful relatives, until her troubled twin brother disappears mysteriously. Convinced that he is still alive, she will stop at nothing to find him, even if it means uncovering long-buried secrets. Vikram, a third-generation storm refugee quarantined with thousands of others in the city's impoverished western sector, sees his own people dying of cold and starvation while the elite of Osiris ignore their plight. Determined to change things, he hopes to use Adelaide to bring about much-needed reforms, but who is using who? As another brutal winter brings Osiris closer to riot and revolution, two very different people, each with their own agendas, will attempt to bridge the gap dividing the city, only to find a future far more complicated than either of them ever imagined. Osiris is the beginning of an ambitious new science fiction trilogy exploring a near-future world radically transformed by rising seas and melting poles.

A boat is shipwrecked on Patagonian shores, and rumors abound that it has come from the lost city’ Osiris, believed to have been destroyed over 50 years ago. The implications are wide-reaching and acutely political, for in the eyes of the world Osiris is only a collection of fables. Pilot and cartographer Ramona, recently returned to the island of Tierra del Fuego, has a broken plane, and the only person who can fix it for her is the Antarctican, Taeo, a political exile desperate to find a way back home. Glimpsing an opportunity for redemption, Taeo discovers there is one survivor of the shipwreck: the sole proof that Osiris exists. He and Ramona find themselves caught up in a perilous conflict of interests over the secret of the sea city, a secret which will have severe repercussions on their lives, their homes, and their loved ones.

Fleeing from her family and the elitist oppression of the Osiris government, Adelaide Rechnov has become the thing she once feared, a revolutionary. But with the discovery of a radio signal comes the stark realization that there is life outside their small island existence. Adelaide’s worries are about to become much bigger. Meanwhile, as rumour spreads on the mainland, many head to the lost city of Osiris with their own devious objectives. But in a world where war is king and only the most powerful survive, there can only be one victor… The thrilling, epic finale to The Osiris Project
