Excerpt:
Little about Lunel, nestling in France's serene, picturesque Camargue region between Nimes and Montpellier, initially sets it apart from other small southern towns.
In cars or on foot, locals and visitors cross paths with Muslim women pushing prams along impossibly narrow streets. Come late afternoon, high school pupils laugh and talk in the warm sunshine. Cafe society seems to be thriving.
But up to 30 inhabitants of Lunel succumbed to the lure of foreign fighting. Young men, radicalised under peer group pressure or by persuasive aspects of social media, headed to Syria or Iraq, and were followed by young women eager to be their brides.
Eight of the men, including a Jewish convert said by acquaintances to have changed almost overnight from being a Led Zeppelin fan to embracing militant Islam, were killed in the conflicts.
