One knock at the door, and Stefania has a choice to make...

It is 1943, and for four years, sixteen-year-old Stefania has been working for the Diamant family in their grocery store in Przemysl, Poland, singing her way into their lives and hearts. She has even made a promise to one of their sons, Izio -- a betrothal they must keep secret since she is Catholic and the Diamants are Jewish.

But everything changes when the German army invades Przemysl. The Diamants are forced into the ghetto, and Stefania is alone in an occupied city, the only one left to care for Helena, her six-year-old sister. And then comes the knock at the door. Izio's brother Max has jumped from the train headed to a death camp. Stefania and Helena make the extraordinary decision to hide Max, and eventually twelve more Jews. Then they must wait, every day, for the next knock at the door, the one that will mean death. When the knock finally comes, it is two Nazi officers, requisitioning Stefania's house for the German army.

With two Nazis below, thirteen hidden Jews above, and a little sister by her side, Stefania has one more excruciating choice to make.

Author of Reese's Book Club YA Pick The Light in Hidden Places, Sharon Cameron, delivers an emotionally gripping and utterly immersive thriller, perfect for fans of Ruta Sepetys's Salt to the Sea.

In 1946, Eva leaves behind the rubble of Berlin for the streets of New York City, stepping from the fiery aftermath of one war into another, far colder one, where power is more important than principles, and lies are more plentiful than the truth. Eva holds the key to a deadly secret: Project Bluebird -- a horrific experiment of the concentration camps, capable of tipping the balance of world power. Both the Americans and the Soviets want Bluebird, and it is something that neither should ever be allowed to possess.

But Eva hasn't come to America for secrets or power. She hasn't even come for a new life. She has come to America for one thing: justice. And the Nazi that has escaped its net.

Critically acclaimed author of The Light in Hidden Places Sharon Cameron weaves a taut and affecting thriller ripe with intrigue and romance in this alternately chilling and poignant portrait of the personal betrayals, terrifying injustices, and deadly secrets that seethe beneath the surface in the aftermath of World War II.
