Synopsis
“Prime Minister Churchill, the Witches of Britain are at your service…”
As World War II rages across Europe, Britain faces its darkest hour. Emerging from centuries of secrecy, the Royal Academy of Witches offers its clandestine aid to the British war effort.
Lydia Polk, second-in-command to her coven, is dispatched on a high-stakes mission across war-torn London and occupied France to locate a spellbook of unspeakable power. But tracking down the Grimorium Bellum is only half the battle—the ancient book possesses a dark agenda of its own, and not all witches agree on which side of history they should stand.
