The Mahogany Ship

An ancient shipwreck.

A pyramid half a mile below the sea.

And a puzzle that must be solved before it destroys humanity.

More than 200 years ago, the Emily Rose became shipwrecked on the southern coast of Australia. The survivors were forced to walk nearly a thousand miles through the unexplored land to reach the only established settlement, Sydney Cove.

Hundreds of miles into their journey they discovered something strange. Something that couldn’t possibly exist.

In present day, Sam Reilly and his team of ocean investigators are exploring the unknown cause of the widespread death of sea life within the Gulf of Mexico.

The two mysteries may just be entangled, and failure to solve them both will result in the greatest threat to ever face the human race.
