Kohate

In a galaxy where commercial police forces operate on profit motives, more arrests mean more funding — so laws grew stricter, and prison overcrowding created the Justice Auction System. Prisoners are now simply sold to the highest bidder. You have been purchased by BioMass Labs for testing at their remote facility: Kohate. Nobody knows what they do there. Nobody who has gone in has come back out. You belong to them now and must survive whatever tests they assign you. A sci-fi survival thriller about a system so broken it sold a human being.
