Yes, generally they are suitable for a wide range of ages. They often contain elements of adventure, mystery, and friendship which can be enjoyed by both kids and young adults.
Adventure is a major theme. The characters are constantly on exciting quests. Another theme is friendship, as the characters rely on each other. Mystery also plays a big part as they often have to solve strange phenomena.
I'm sorry, I don't know Sarah Jane Salazar personally, so I can't provide her life story specifically. But generally, a life story could include details like where she was born, her family background, her education, and her career path.
Adventure is a very common theme. Given her character's history of traveling with the Doctor and having her own adventures, many fanfictions continue this trend, taking her on new and exciting missions. Another common theme is friendship, especially her relationships with the Doctor, her companions, and the friends she makes in her own series. It often explores the deep bonds she forms.
One possible adventure in a fanfic could be Ahsoka and Luke teaming up to face a new Sith threat. Ahsoka's experience with the Clone Wars and her knowledge of the Force could combine with Luke's Jedi training. They might travel to a long - forgotten planet in search of an ancient Jedi artifact that could help in their fight against the dark side.
Leia and Luke could find themselves in a situation where they have to deal with a new Sith Lord. This Sith Lord has a unique power that they have never encountered before. They would have to quickly figure out how to counter it, perhaps by combining their own powers in an unexpected way.
Social media platforms can also be a source. Look for Doctor Who or Sarah Jane Smith fan groups on Facebook or Twitter. Some fans might post links to their fanfiction there or discuss where to find the best ones.
One interesting fanfiction could be where Sarah Jane Smith's pregnancy is a surprise to her friends. In this story, her companions like the Doctor might initially be shocked but then become extremely protective. They would help her face the challenges that come with pregnancy, such as dealing with alien threats that might target her unborn child.
She could be pregnant with a half - alien child. This would bring a whole new set of challenges as she tries to protect the child from those who might want to use it for their own purposes. Also, she has to figure out how to raise a child with such a unique heritage.
