The Nazis' dark secrets are revealed, in a tense and compelling thriller from bestselling author Ian Slater.

June 1944. The moment has come. The Allied pincers are closing in. Hitler has already ordered his jet fighters, V-1 flying bombs, and V-2 rockets into action. Now, in a desperate bid to keep his war machine churning, it is time for the führer to use the most secret weapon of all.

For G.I. David Adam, it's a mission into hell. To stop Hitler's mad plan will take him and others into the lion's den, under the shadow of the SS—where exposure means death, but being killed is better than being taken alive…

Only a handful of courageous men and women can stop Hitler's terrifying superweapon, and helped by French resistance fighters, Jewish slave laborers, and members of the Polish underground, these few will fight the most critical battle of the entire war.
