Novel Shorts

I am currently working on a science fiction novel, which I plan to publish. Thus I am not posting said novel on-line.

However, in order to better help me create realistic characters (not to mention a realistic past), I've decided to write a variety of short stories that incorporate them at various stages in their lives.

This story also involves time travel, so I plan on writing several stories that may or may not (probably not) involve said characters in various locations in time. This will (hopefully) help me create credible settings in my novel.

Any input that you can give will be greatly appreciated. Please let me know if you find the characters credible or the settings appropriately described. If you find something that just rings wrong, please tell me! I don't want to incorrectly incorporate something into my novel that didn't happen!

Thanks again for all your help!
