Killing Tiffany Hudson

Killing Tiffany Hudson is one of two stories in the Apocalypstick collection. It is the story of two genetically altered people who must decide the fate of humanity.
Here's the cover blurb:
Is there any line you wouldn't cross to save the life of a loved one? Is there any price you wouldn't pay? A young man battles with the consequences of his answers to these questions, in this post-apocalyptic short story, where right masquerades as wrong, weakness as strength, and deadly monsters as... camels? Well, sometimes, yes.
