Sims is a science fiction novel by F. Paul Wilson that explores a near-future event where Humanzees (Human-Chimpanzee hybrids) are created as a de facto slave race. In the near future, there have been amazing advances in genetics research. Through gene therapy, many deadly diseases have been cured. The SimGen Corporation has created a transgenic species called SIMS, creatures that are part chimpanzee and part human, and are treated as slaves. Suddenly a group of sims working as caddies at a golf course decide they want to unionize. They hire lawyer Patrick Sullivan to represent them, and Sullivan begins to ponder whether or not sims are entitled to equal human rights.
