"Hildegard is a welcome addition to the ever-expanding ranks of religious sleuths who populate the pages of medieval mysteries." - Booklist
In the midst of a long, bleak winter in the year 1383, flooding brought famine, famine brought disease, and The Black Death visited town after town.
Into this watery world, against a background of plague and the turmoil of the Hundred Years' War, a brave and brilliant nun, Abbess Hildegard, embarks on a quest for a precious relic, the Cross of Constantine.
Strong-willed and independent, she will need remarkable skills to survive. For with the English Crown at stake, there are many who want her mission to fail—and one, above all, who plans a deadly revenge.
