At the behest of a wealthy geneticist researching the minute genetic differences that separate humans from chimpanzees and control the way the two species think and learn, a number of U.S. scientists have been asked to raise and study bonobo chimpanzees in their homes. One such chimp is Umber, placed with Dr. Jim Dutton, an anthropology professor. Umber, however, is startlingly different from the other chimpanzees Dutton has studied. Quick to learn, Umber soon acquires a prodigious sign language vocabulary and manipulates the computer, tools, and kitchen appliances with remarkable ease. After comparing notes with other host families, Dutton starts wondering if the chimps were somehow altered. The question galvanizes Dutton and Canadian journalist Valerie Radin to seek the truth-a truth that will soon lead to a horrifying discovery.
