Bestselling authors Goyer (Night Song
) and Yorkey (Every Man's Battle series) collaborate for the first time in this WWII novel that centers around real historical events. Goyer and Yorkey open their text with a brief primer on the unsuccessful 1944 attempt on Adolf Hitler's life (dramatized in the movie Valkyrie
). This story takes off immediately following that event; Hitler, bent on revenge, goes after anyone remotely capable of injuring him and sets up countless spies in key positions to take out persons with even the slightest Jewish heritage. Gabi Mueller, a Swiss-American woman who works for the American Office of Strategic Services, finds herself enlisted in safecracking, a job for which she is highly skilled. As Gabi seeks to make a difference in the face of evil, she is asked to help rescue a German physicist who is working on the atomic bomb. While her loyalties are not in question, Gabi struggles over whom to trust as the stakes become life and death. Goyer and Yorkey do a fine job presenting realistic characters and wartime scenarios; some readers, however, might find the sheer number of plot locations difficult to follow. (Oct.)
