Fans of Dan Brown and Clive Cussler will be unable to resist this thrilling new Jack Howard action adventure from Sunday Times bestseller David Gibbins.

Underwater archaeologist Jack Howard is back with a dangerous mission to uncover a shocking secret which could rewrite history...

In 1890, a British soldier emerges from the depths of a Cairo sewer.

Their mission will take them across the globe, down to the darkest depths of the Red Sea, and back through Egyptian history to the bloody reign of Akhenaten, the Sun-Pharaoh - and keeper of a devastating secret...
