Lamb built a career with his writing from an early age. He began writing for
pulp magazines, writing stories about the mountains of
Afghanistan and the Russian steppes. The success of Lamb's two-volume history of the Crusades led to his discovery by
Cecil B. DeMille, who employed Lamb as a technical advisor on a related movie,
The Crusades. He also wrote several novels which were almost like dramatized biographies; he did not invent much beyond known history. Lamb produced several fantasy novels featuring
lost worlds. These included
Marching Sands, about a lost city of Crusaders in the Gobi Desert.
A Garden to the Eastward features a hidden tribe living in an extinct volcano in Kurdistan. == Awards ==
