What has the author Lois Clark written?

There seems to be some confusion. There is no widely known author named "Lois Clark." It's possible you're thinking of:

* Lois Lane: A fictional character from the Superman comics and related media. She is a reporter for the Daily Planet.

* Lois McMaster Bujold: A well-known science fiction and fantasy author. She's known for the Vorkosigan Saga and other works.

If you can provide more information, I might be able to help you find the author you're looking for.
