"Pilgrim seeks sinners for mutually beneficial arrangement. Seven Deadlies a specialty." With these words Ailsa Piper's journey begins. Less than a month later she finds herself hiking through olive groves and under translucent pink blossoms, making her way from the legendary city of Granada, towards the cliffs at Finisterre in the far north-west of Spain. On her back she carries an unusual cargo - a load of sins. In the tradition of medieval believers who paid others to carry their sins to holy places, and so buy forgiveness, Ailsa's friends and colleagues donated sins in order to fund her quest. She's received anger and envy, pride and lust, among many. Through glorious villages and inspiring landscapes, miracles find her. Matrons stuff gifts of homemade sausages into her pack. Angels in both name and nature ease her path. Sins find her too. Those in her pack and many others tempt her throughout her journey.
