I'm supposed to write this short story to send in for my English class, and I have NO clue what to write about!

Ideas I Am Pondering:

- A nurse in the Yellow Fever. She is young, but has lost both parents to the illness and is staying wherever she is needed.

- A girl with present day monsters under her bed. They are called Night Terrors, and they are demons sent from hell to torture children.

- A boy, kidnapped by a mysterious girl who can read the stars and has seen the future, mistaken for his twin brother whose plot it is to overcome the kingdom. The girl intends to put his blood on the Sacred Alter as a sacrifice to the stars to stop the prophecy from occurring.

Hepp! Any ideas? Anyone like the ones I have so far?
