Christopher Ride's new bestseller is a breathless action adventure - with a time travel twist - set in the lost city of the Incas.
It's 1908 and the Golden Cube of the Sun God, safely hidden in Peru for over 500 years, has been stolen. Made of pure gold, the cursed object has the power to control the minds of men - and bloody revenge is its aim.
The most powerful man in South America - Bishop Francisco - has succumbed to its torment. A man has been crucified. Innocents are being murdered. The Peruvian army has been mobilised. Everyone is afraid.
Only one man is immune to its spreading evil: Wilson Downling, the Overseer, a man transported from the future who must carry out a series of vital missions encoded in the Dead Sea Scrolls.
His latest assignment had seemed simple enough: assist the hapless American explorer Hiram Bingham to discover the lost Inca city of Machu Picchu. But history is wildly off course and everything is different now.
