“The Big Books of the main series deal with the lives and times of Claire and Jamie Fraser. The shorter novels focus on the adventures of Lord John Grey but intersect with the larger books (The Scottish Prisoner, for example, features both Lord John and Jamie Fraser in a shared story). The novellas all feature people from the main series, including Jamie and/or Claire on occasion. The description below explains which characters appear in which stories.
Most of the shorter Lord John novels and novellas (so far) fit within a large lacuna left in the middle of Voyager, in the years between 1756 and 1761. Some of the Bulges also fall in this period; others don’t.”
