These two novels are part of Scott's Waverley Novels series, set against the backdrop of 18th-century Scotland. Old Mortality explores the Covenanters' rebellion and the struggles between religious factions, while The Heart of Midlothian follows Jeanie Deans, a woman of great moral integrity, as she seeks justice for her sister in a story intertwined with political and social unrest. Both novels highlight Scott's ability to blend historical events with rich character development.
