They can be heroes. Just like in some superhero - like science fiction, sisters with special powers can save the world. For instance, they could have telepathic abilities and use them to stop an evil alien invasion.
In many science fiction works, sisters can be a force for change. They might oppose a dystopian regime or fight for the rights of a marginalized group. Their sisterhood gives them the strength and motivation to take on these challenges, as seen in some post - apocalyptic novels where sisters lead the way in rebuilding society.
It depends on the content and the author's intention. But if it's based on real events or people, it might be nonfiction. If it's made-up stories and characters, then it's fiction.
In my opinion, 'Sisters' can be considered realistic fiction. The story reflects common human experiences and emotions, and the settings and events seem plausible and relatable.
These sisters are also role models in fiction. They teach values like kindness, loyalty, and selflessness. Their actions inspire other characters in the story and can also be an example for readers or viewers to follow in real life.
One famous pair of siblings in fiction is the Pevensie children from 'The Chronicles of Narnia'. Peter, Susan, Edmund, and Lucy are brothers and sisters who enter the magical world of Narnia. They each play important roles in the various adventures and battles against the forces of evil in Narnia. Peter is the eldest and a natural leader. Susan is the gentle and practical sister. Edmund starts off a bit wayward but grows into a brave character, and Lucy is the youngest and often the first to discover things in Narnia, full of faith and courage.
One common theme is loyalty. Sisters in these fictions often show great loyalty to one another, through thick and thin. For example, in 'Little Women', the sisters support each other's dreams and are there for each other during hard times. Another theme is competition. Sometimes sisters compete for things like parental attention or their own achievements, as seen in some family - centered sister fictions.
The Baudelaire sisters, Violet, Klaus, and Sunny, from 'A Series of Unfortunate Events'. They are orphans facing a series of misfortunes and the evil Count Olaf. Violet is an inventor, Klaus is a reader and researcher, and Sunny has very sharp teeth and her own unique ways of helping her siblings.
Take the March sisters for example. Meg is more traditional and ladylike, desiring a stable family life. Jo is a tomboy, very passionate about writing and her independence. Beth is gentle and kind - hearted, while Amy is more interested in art and has a bit of vanity. They all support and sometimes argue with each other.
