On a frigid, windswept day in Scotland’s Western Hebrides, Eleanor Bruton’s body is discovered on the shore. Little did Eleanor’s family know that she was harboring a dark and all-consuming secret --- a scrap of fraying embroidery that seems worthless at first glance. For over a century, two rival organizations of women have gone to deadly lengths to secure the valuable artifact in the hopes of finding the original medieval manuscript from which it was torn. When Dr. Anya Brown garners international attention for her translation of the cryptic Folio 9, she is handpicked by Diana Cornish, a professor and high-ranking member of the Fellowship, to join the exclusive Institute of Manuscript Studies in St. Andrews. Unbeknownst to Anya, she’s been recruited at great personal danger to translate ancient texts that the Fellowship believes critical to their mission.
