Car Johnson is a fictional character living in the mind of Rebekah Webb. She writes comedy, horror and anything that strikes her fancy.
Rebekah Webb (1980- hopefully a long time) was born in Los Angeles, California to human parents, which was a good thing, since alien parents would have been difficult to explain at school. She lived in Reno, Nevada for a while, then moved back to California. Nothing extraordinarily exciting happened to her in her lifetime, probably because of a lack of alien DNA. (Well, so far. She could end up a part of a super-intelligent squirrel conspiracy. You never know.)
