Strong as Death. Number 4 in series

As a former novice of the Convent of the Paraclete, the young Catherine LeVendeur's life has been filled with adventure and intrigue. When she fell in love with her Saxon nobleman, Edgar, it was hoped that married life would settle this headstrong woman. But fate will have its way and, after suffering several miscarriages, Catherine is inspired by a prophetic dream that she and Edgar must embark on a pilgrimage to the fabled monastery of Compostela, to petition for a child.
During their journey Catherine and Edgar encounter mad monks, bawdy crusaders, and a motley collection of pilgrims whose past deeds bind them all in a bizarre game of chance. When several pilgrims are gruesomely murdered, the trail of evidence points to an old and blackening sin, and a hidden villain whose quest for revenge may lead to Catherine's untimely death .
