From Sunday Times bestselling author Graham Brown, co-author (with Clive Cussler) of The Pharaoh's Secret

A coveted treasure. A perilous mission. A dangerous secret that could change the world...
Former CIA-agent Hawker has been black flagged by his own government and Interpol and the State department have issued a warrant for his arrest. All Hawker wants to do is find a way back home that doesn't involve a prison sentence or a body bag.
Government operative Danielle Laidlaw is his way out. She needs a pilot and a security consultant for her mission to discover the lost Mayan city of Tulan Zuyu. In return for his services, she promises Hawker his life back.
But as an unseen enemy stalks the rainforests, leaving battered corpses in its wake, they are about to discover that they are not the first - and they are not the only people looking for Tulan Zuyu and the secrets it may hold.
