All Things Hidden

From #1 New York Times bestselling author Sherrilyn Kenyon comes a supernatural historical thriller, perfect for fans of The Nightingale by Kristin Hannah.

When Maria Bertram is summoned to Czechoslovakia for a secret mission against the Allies, she has absolutely no idea what the Germans have planned. Her goal is to avenge her family, who were brutally murdered by a Nazi SS officer who used them as an example to scare the rest of her town into submission. The last thing she expects is to meet a mysterious man who is as equally determined to stop the Wehrmacht as she is.

Dusek Fara is much, much more than he appears. He knows the truth behind the Höllenlandschaft the Nazis are trying to build, and he has one task: Stop the Nazis before they unleash an evil that won't just end the war but the world. His is a sacred task, and he will do whatever it takes--including kill Maria.

But war is never simple, and the war Dusek is fighting has been going on for thousands of years. Never has the world been closer to annihilation. He has one chance to finish what he started, or all his sacrifices will have been for nothing. The one thing he knows for certain is that Maria--with the cursed powers she never asked for--is the key. She will either end the war or end the world.
