Not exactly a sequel, but a novel written in parallel with the superb The Lady Tree, in other words sharing some of the same characters but entirely independent of the first book.

Is there such a thing as a werewolf? Quicksilver is no horror story, but in its fabulously vivid recreation of 17th Century England and Holland, it portrays a young man suffering from lycanthropy - when a man believes himself to be a wolf. This was a time when medical science was undergoing vast changes and the discovery of the New World was yielding up all sorts of new plants and drugs, and Christie Dickason weaves a pulsating story of intrigue, adventure and romance around this extraordinary set of circumstances.
