Greg Campbell knows a bit about adventure and horror. The Fort Collins freelance writer and dad was held at gunpoint and hung with the boys of Soldier of Fortune for his first book, The Road to Kosovo. But he upped the danger quotient in 2002's Blood Diamonds, his investigation into the Sierra Leone diamond trade. In that West African country, Campbell found villagers who'd had their hands chopped off by machetes to ensure their cooperation with the Revolutionary United Front militias; he also witnessed instances of ethnic cleansing and mass rape. In his 282-page book, he explores the role of diamonds in financing the country's civil war and terrorist organizations -- including al-Qaeda -- and their effect on everyday people. Campbell, who has given up the war-correspondent life, is currently posted Stateside, as the founding editor of the Fort Collins Weekly.
