A secret buried in coral. A drug that rewrites the mind. A coastline on the edge of collapse.

When conservation agent Gideon Marais is sent to investigate a remote East African reef, he uncovers a conspiracy far more dangerous than poachers and smugglers. Synthetic drugs harvested from deep-sea coral are flooding the black market - and someone will kill to keep it that way.

As Gideon dives deeper, he finds himself entangled in a web of bio-crime, corporate espionage, and environmental sabotage, stretching from the reefs of Mozambique to the boardrooms of Johannesburg. And when a covert billionaires' syndicate enlists his help, Gideon must decide how much of his soul he's willing to trade to stop a chemical arms race.

From the award-winning Gideon Marais series, Requiem for the Reef is a high-octane thriller where science meets sabotage in the most beautiful - and brutal - corners of the ocean.
