QUEEN OF DIAMONDS by R. O. Palmer:: Ngoc Soan is a Vietnamese refugee who, following in her fathers footsteps, has built a thriving diamond company in Philadelphia. She decides to defy the De Beers diamond cartel which controls the world supply, by seeking to exploit a revolutionary mining discovery - a discovery that De Beers will do anything to suppress. Other characters include a sinister Russian, a brilliant geologist, a rival tycoon and Ngoc's own ambitious niece. Add in Paul Weeks, master of surveillance can disguise and you have the makings of a great read. Enjoyable.
