ISIS Exposed: Beheadings, Slavery, and the Hellish Reality of Radical Islam

Terrorism expert Erick Stakelbeck pulls back the curtain on ISIS, the violent terrorist organization spreading death and hate in the Middle East.

Stakelbeck, a veteran national security reporter and a leading authority on the Middle East, has produced the definitive guide to America's most recent and most frightening enemy.
