Lizzie Browning loves nothing more than her tiny, island-home of Guernsey, but when German bombs drop on her crystal beach, her peaceful world explodes. For months, the big war in Europe has been nothing more than stories in the paper, but as the enemy takes over Guernsey, the war rushes to her doorstep. For Lizzie, younger brother Andre, and cousin James, the time to escape is now, and they know just how to do it.
Phillip Seifert, the odd boy from down the street, has all the markings of a genuine Nazi-lover. Lizzie knows better than to trust him, but he somehow manages to weasel his way into James' good graces. Phillip joins the gang in their audacious escape plan, and Lizzie can do little more than pray he doesn't get them all shot. But Lizzie soon learns that God doesn't always answer prayers in the way she expects. He might actually plan for them to live under Nazi rule...forever.
