One popular fiction is 'The Other Queen' by Philippa Gregory. It weaves a story around Mary Queen of Scots and her relationships within the complex political and social environment of the time.
Another type of fiction might be more centered on her love life. Mary was married multiple times, and fictions might explore how her marriages affected her political standing and her personal life. They might also show how her romantic relationships were intertwined with the power plays in Scotland and her attempts to secure her throne.
There are also many historical fictions that depict her life in a more dramatic way. For example, some fictions focus on her relationship with Queen Elizabeth I of England. They show how their rivalry was not only a personal one but also deeply rooted in the political and religious differences between Scotland and England. These fictions often explore the power struggles, the intrigues in the courts, and the difficult choices Mary had to make.
