Flying Above the Hindu Kush — M.L. Buchman / Matthew Lieber Buchman

Night Stalkers Captain Tyra Walker flies deep into enemy territory. It seems that “flight” has become her whole life's story, whether in her Arkansas hometown or in a kick-ass helicopter.Delta operator Major Norm Lawrence stepped away from his past and only thinks about the next mission, until Tyra crosses his path.When Tyra's past meets Norm's present deep in the Hindu Kush Mountains -- a land where military arms flow from Pakistan into Afghanistan -- they'll need each other to survive the future.
