Lorenzo Vidino's Al Qaeda In Europe: The New Battleground Of International Jihad provides an excellent companion piece, considering how Europe has become a key battleground on the War on Terror. This is the first book in English to examine Islamic roots and terrorism in Europe, comes from a Deputy Director of The Investigative Project, and examines exactly how terrorists raise money, communicate, and operate through hidden cells across the continent. Original documentation from a dozen nations accompanies transcripts of Al Qaeda conversations and chapters which examine particular plots.
