I'm trying to write a particular kinda story, but I don't know where to get started beyond describing what I want. •*Character: That I have figured out, her name's Janet and she's a jill-of-all-trades. She's an eccentric libertine who, while doing rather well in a cushy industrial nation environment, would also do well in a crisis situation. Personal power is the key term with her. •*Cliché: By this I mean a setting full of simpletons who can't think beyond their very limited social environment. High schoolers and their petty dramas for example. •*Cataclysm: WHAM! The entire environment changes. Military invasion, alien contact, the emergence of the paranormal, and so forth. Guess who everyone turns to for help? So, what're the concept's flaws? What can make it work? What have I left out or left unclear? What similar things could I write about instead?
