"Elena Garcia knows that the mission she has been tasked with is her most dangerous yet. With a tearful goodbye to the man she has grown to love, the dark-eyed and warm-hearted Santiago Lozano, she hurries to catch the train to the drop-off point, the coded maps she is delivering for the resistance concealed in a pack of playing cards in her purse. As she leaves the underground meeting, she hears heavy footsteps closing in behind her. Her heart pounds, and a dark figure comes into her line of sight. Expertly fighting off her attacker, Elena races back to the station, barely making it onto the train. She is forced to confront the worst: her cover is blown and now nowhere will be safe. Somebody close to her is a traitor, but when you live in the shadows, how do you know who you can really trust? To stay alive, Elena must flee the country -- and that means leaving Santiago behind. But she refuses to abandon her mission while Europe is still in the clutches of the enemy, and she will not leave Santiago to face the wrath of the Gestapo alone. But when Elena uncovers that the love of her life has been having meetings with high-ranking government officials and hears German officials greeting him by name in the street, it’s clear that Santiago has his own secrets. Elena must now ask herself: should she risk everything to save Santiago... or was he the one who betrayed her to the enemy? And now, with millions of innocent lives across Europe at stake, how can she know what is the right choice?" -- Amazon.com
