Isa de Smit was raised in the vibrant, glittering world of her parents' small art gallery in Amsterdam, until the Nazi occupation began. Masterpiece by masterpiece, the Nazis are buying and stealing her country's heritage. So when the unpaid taxes threaten her beloved but now empty gallery, Isa decides to make the Nazis pay. She sells them a fake -- a Rembrandt copy drawn by her talented father. When she discovers that her best friend Truus is part of a resistance ring trying to smuggle Jewish babies out of Amsterdam, she realizes that she knows how to get the money: one more forgery, a copy of an exquisite Vermeer, and the Nazis will pay for the rescue of the very children they are trying annihilate. To make the sale, though, Isa will need to learn the art of a master forger, before the children can be deported, and before she can be outed as a collaborator for selling art to the Nazis. And she finds an unlikely source to help her do it: the young Nazi soldier, a blackmailer and thief of Dutch art, who now says he wants to desert the German army.
