As World War I rages, there are evils—both living and dead—that only a witch can see in a spellbinding novel by the Amazon Charts and Washington Post bestselling author of The Raven Spell.

With her husband off fighting at World War I’s eastern front, Petra Kurková embraces her fleeting freedom, roaming the city at night with her camera. A born witch, she’s discovered that she can capture the souls of the dead on film. Her supernatural skills don’t go unnoticed by the enigmatic Josef Svoboda. He’s recruiting a team of sorcerers to infiltrate the front lines, where the bloodshed of combat has resurrected foul creatures. Petra’s unique abilities will be needed against the most dangerous enemies of all—those ever present, undead, and unseen.

Deep in the cursed Carpathian Mountains, the ragtag team meets with an emissary of an ancient organization founded to maintain balance between worlds. Photographing the escalating horrors is beyond anything Petra imagined. So are the secrets among her fellow witches. But Petra can’t turn back. Not before she discovers her husband’s fate and the myriad ways her magic is manifesting. To defeat an occult foe, Petra must release the power she’s been concealing for so long, or risk damning a war-torn world to ashes.
