Just a few hundred genes separate humans from chimpanzees. Suppose you altered chip DNA, create a new species of worker, somewhere between Simian and human? SimGen, a powerful new Corporation has done just that. Using their genome, they have begun breeding Sims by the hundreds, leasing them out to serve as cheap manual labor in factories and sweatshops. There are protests, of course, but somehow SimGen has managed to squash any attempt to ban or regulate the production of sims, as a young lawyer Patrick Sullivan is about to discover. But SimGen has secrets, beyond their patents and propriety knowledge Dreadful secrets that they will go any length to protect.
