Her name is Sarah.  That is all that she can remember.  They pulled her from the wreckage of a starship that crash landed on this planet.  They thought that she was dead but she got better.  Now these people that call themselves humans are holding her in a secret government facility.  They want her to tell them the secrets that will unlock the technology that she was found with.  Until her memories come back there is not much she can do about that.  She suspects that they won't like the answers to their questions even if she could answer them.   Now there is a strange hunger beginning to manifest itself in her body.  Nothing will satisfy it and she can't tell her captors what it might be. The food they supply her with seems to lack a specific nutritional ingredient.  She doesn't dare tell them that they are starting to look tasty.
