From publisher blurb:
BEWARE THE POLYMER THRALLS!
They're relatively cheap, they don't ask questions, and they will get the job done or they will cease their existence in trying. They're Polymer Thralls... artificial humaoid beings made of a single piece of plastic and they can be had for a low, low price!
Nevermind that no one really understands how they walk and talk and think... no, really, never mind. Bad things happen to people who ask too many questions about the Polymer Thralls.
So drop this capsule in some warm water and enjoy your new minion, or dress it up a little, hand it a gun, and watch it go to town on things that you don't like! Just... seriously.... stop asking so many questions.
