D-Day is approaching. They don?t know where or when, but the Germans know it?ll be soon, and for Felicity "Flick" Clariet, the stakes have never been higher. A senior agent in the ranks of the Special Operations Executive (SOE) responsible for sabotage, Flick has survived to become one of Britain?s most effective operatives in Northern France. She knows that the Germans? ability to thwart the Allied attack depends upon their lines of communications, and in the days before the invasion no target is of greater strategic importance than the largest telephone exchange in Europe. But when Flick and her Resistance-leader husband try a direct, head-on assault that goes horribly wrong, her world turns upside down. Her group destroyed, her husband missing, her superiors unsure of her, her own confidence badly shaken, she has one last chance at the target, but the challenge, once daunting, is now near-impossible. The new plan requires an all-woman team, none of them professionals, to be assembled and trained within days. Code-named the Jackdaws, they will attempt to infiltrate the exchange under the noses of the Germans ? but the Germans are waiting for them now and have plans of their own. There are secrets Flick does not know ? secrets within the German ranks, secrets among her hastily-recruited team, secrets among those she trusts the most. And as the hours tick down to the point of no return, most daunting of all, there are secrets within herself?
