In this debut novel from Ausma Zehanat Khan, an evil force known as the Talisman rules over the world, led by a man known as the One-Eyed Preacher. His followers are a superstitious patriarchy that oppresses women and suppresses knowledge, and their influence is growing. The only people who can stop them are the Companions of Hira, a group of women who draw power from a scripture called the Claim. They’ve been fighting against the Talisman for years, and uncover something that they might be able to use as a weapon against it: the Bloodprint, a text that the One-Eyed Preacher tried to eradicate.
