Description -
In a remote corner of Zangara, a small republic in Africa, lies Crystal Mountain. At certain times of the day the mountain emits a strange glow. Only Sir James Manson knows why. The mountain contains ten billion dollars worth of the world's most valuable mineral, platinum. 

"Not only exciting but truly surprising"—Atlantic. Now the only question is, how to get hold of it. Sir James knows how. Invade the country with a band of savage, cold-blooded mercenaries. Topple the government and set up a puppet dictatorship. Unleash the dogs of war.
