Bluebird by Sharon Cameron

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.
