Heather Marie Mercer is an American who was one of 24 aid workers arrested in August 2001 by the Taliban in Afghanistan in connection with their work with the Germany-based Christian aid organization Shelter Now International. She, along with seven other Western aid workers and their sixteen Afghan coworkers, was arrested on August 3, 2001, and put on trial for violating the Taliban prohibition against proselytism. She was held captive in Kabul until anti-Taliban forces freed her in November 2001. She co-authored a book with her fellow captive, Dayna Curry, published in 2002 and entitled Prisoners of hope: the story of our captivity and freedom in Afghanistan.
