Nightshade

British spy Livy Nash has never had many friends. But fellow agent Margot Dupont was the exception to the rule. At least, until she disappeared during one of their missions in World War Two, never to be heard from again. But when the British pick up Margot's call sign - NIGHTSHADE - years after the war, Livy can t help the glimmer of hope that she might see her old friend again. As Livy is pulled deeper into the shadows of treachery, the possibility of finding Margot alive diminishes as the danger grows. How much will she have to sacrifice to find a friend she thought she'd lost forever?
