Beyond the Light Zone (Paperback)

The mutilated body of a diver is found in the Yucatan peninsula, far from the coast. In Europe a deadly illness is sweeping through the continent. When cave diving expert Mike Summers returns to Mexico and crosses paths with maverick government agent Raphael Rodriguez, he soon finds himself plunged into a world of intrigue and terror. Rodriguez has been sent to monitor drug movements along the Yucatan coastline, Mike is trying to unravel the mystery of his friend's death, but both find their investigations linked to the area's ancient subterranean cave systems and to events which shook the local Maya civilisation some 500 years previously. "Steve Turley's second adventure thriller is another polished page-turner, written by an expert in the undersea world of sub-aqua, and an adventurer in his own right. A classy and enjoyable read."
