"Castle Dangerous" is the last of Walter Scott's "Waverley" cycle of historical novels. The story takes place shortly after the death of William Wallace in the Scottish War of Independence. Basically a romantic tale, the narrative follows a fair lady and her pledge of marriage. With romantic triangles, mysterious identities, battles, and sword duels, "Castle Dangerous" is a satisfying conclusion to Scott's longish tradition of historical novels. Despite being his "swan song", it still remains a pleasant and highly recommendable read.
