Book excerpt: Magda stands in the moonlit cemetery waiting for the spell to work, for her lover to return. But what’s done can’t be undone, and Magda will learn she should have left him in the ground. When twins Avery and Chloe Parsons receive a cryptic letter and a sinister-looking book filled with illegible scrawls from their grandmother, the sisters set out for Prague to check on her. Drawn to a cracked crystal ball in a curiosity shop, Chloe discovers it harbors the spirit of their grandmother, who tells them a horrific tale of lust, naïveté, betrayal, and… demons. Armed with a book of dark magick they can’t read and a cracked crystal ball, the twins must stop Magda’s resurrected lover before he releases an unstoppable force that will consume the human world. Across continents and nearly a century, follow the adventures of three strong-willed women: one seduced by evil, one struggling to withstand the lure of power, and one trying to save her family—and the world.
