The Mistress continues the spellbinding adventures of Lenore and Geoffrey whom we first encountered in The Lovers, the first volume of the This Towering Passion saga. The story begins in 1651 with their first Christmas together, at Oxford, hiding from the enveloping Roundheads. Their happiness is soon broken by Geoffrey's exile in France and Leonore's enforced absence from Oxford as rumours spread about her being "The Angel of Worcester." Frequently disguised, she flees from town to city hoping for the day she can be reunited with her golden daughter and her great love, Geoffrey. Eventually, after Oliver Cromwell's death the country tires of no monarch and 1660 sees the Restoration of Charles II. Leonore is there as he rides in triumph through London, but even with all the wild revelry of Restoration London about her she is still poor, downcast and alone. Could not even the favours of the King himself restore her to Geoffrey?
