Marion Glasscoès book provides both a much needed introduction to the field of mystical writing and an explanation of its key writers. It begins by demystifying the religious background, charting the `game of faith', its goals, methods and rules. It then goes on to clarify the nature and growth in mystical experience through an analysis of the key works of the five major medieval English mystic writers: Richard Rolle, Walter Hilton, the anonymous author of The "Cloud of Unknowing", Julian of Norwich and Margery Kempe.
