Inhalt: The year is 1915 and the world is at war. Marta and her father are passengers on the Lusitania, desperately trying to get back home to Germany. While aboard, they must keep their identities hidden or risk being mistaken for enemy spies. Then the Lusitania is attacked by a German submarine. They just make it off the sinking ship, but her father is discovered and detained. Marta suddenly finds herself alone in enemy land. To survive, Marta must draw upon a deep well of bravery she never knew she had. Fortunately, she meets Clare, a young Irish girl who can talk a mile a minute, and her kind family. Believing that Marta is a Dutch refugee, they welcome her into their home. She can't risk letting her new friends know she's actually from Germany — the very nation that the Irish and English are fighting against. But could these people who have shown her nothing but kindness truly be her enemy? Sweeping from the Irish Sea to a cathedral city in England, this story shows us that friendship, especially in times of war, may be the greatest gift of all.
