Bishop's Lynn, England, 1413. At the age of forty, Margery Kempe has nearly died giving birth to her fourteenth child. Fearing that another pregnancy might kill her, she makes a vow of celibacy, but she can't trust her husband to keep his end of the bargain. Desperate for counsel, she visits the famous anchoress Dame Julian of Norwich.

Pouring out her heart, Margery confesses that she has been haunted by visceral religious visions. Julian then offers up a confession of her own: she has written a secret, radical book about her own visions, Revelations of Divine Love. Nearing the end of her life and fearing Church authorities, Julian entrusts her precious book to Margery, who sets off the adventure of a lifetime to secretly spread Julian's words.

Mary Sharratt vividly brings the medieval past to life as Margery blazes her trail across Europe and the Near East, finding her unique spiritual path and vocation. It's not in a cloistered cell like Julian, but in the full bustle of worldly existence with all its wonders and perils.
