The remarkable tale of an Afghan who once fought the Russians, became a protégé of a now-dead freedom fighter who had gone to Harvard, and eventually went there himself, was bought by Morgan Entrekin at Grove/Atlantic for a low six figures from agent Tina Bennett at Janklow & Nesbit. He bought world English rights in the untitled book by Masood Farivar and plans to publish in 2004. Farivar was a young soldier in the Tora Bora enclave when he was taken under the wing of Carlos Mavroleon, a Harvard grad and former bond trader in New York, who helped Farivar get into the U.S. and Harvard and was later killed in Afghanistan under mysterious circumstances. Now a reporter for Dow Jones, Farivar recently returned to his native land to find most of the people he had known dead or fled.
