Secret History of Witches

Brittany, 1821. After Grand-mere Ursule gives her life to save her family, their magic seems to die with her. Even so, the Orchires fight to keep the old ways alive, practicing half-remembered spells and arcane rites in hopes of a revival. And when their youngest daughter comes of age, magic flows anew. The lineage continues, though new generations struggle not only to master their power, but also to keep it hidden.
But when World War II looms on the horizon, magic is needed more urgently than ever - not for simple potions or visions, but to change the entire course of history. / Louisa Morgan
