The author of the acclaimed mystery The Unquiet Dead delivers her first fantasy novel―the opening installment in a thrilling quartet―a tale of religion, oppression, and political intrigue that radiates with heroism, wonder, and hope. A dark power known as the Talisman has risen in the land. Born of ignorance and persecution, it is led by a man known only as the One-Eyed Preacher. A superstitious patriarchy, cruel and terrifying, the Talisman suppresses knowledge and subjugates women. And it is growing.

But there are those who seek to stop the oppressive spread of the Talisman. A resistance formed of the Companions of Hira – a group of rebels versed in the power of ancient scripture, a magic known as the Claim – believe they have discovered the key to destroying the One-Eyed Preacher and his fervid followers: The Bloodprint.
