The main themes in 'The Mercies Historical Fiction' are likely to include social change. Since it's a historical work, it may explore how society evolves over time. There could also be a theme of love and relationships. Characters' interactions with each other, whether it's romantic love, friendship or family bonds, are often important elements in such works. Additionally, cultural identity might be a theme, as different cultures may clash or merge in the historical context.
I'm not entirely sure without reading the book, but usually in historical fictions, there are protagonists who drive the story forward. There might be a strong female character who is at the center of the events, perhaps a woman who has to face great challenges in that historical period.
Since I haven't read 'Small Mercies: A Novel', it's hard to say exactly. However, it could be a story that delves into the lives of ordinary people. It might explore themes such as love, loss, and redemption. The'small mercies' in the title could be those little moments of grace or kindness that the characters encounter during difficult times. For example, a character might be going through a tough financial situation, and a small mercy could be a neighbor offering some food or help without being asked. This could then lead to a transformation in the character's perspective or relationships.
The main theme could be about redemption. Often in such novels, characters strive to overcome their past mistakes and find a new path in life, seeking forgiveness and self - improvement.
