"The Freeman family–Charles, Laurel, and their daughters, teenage Charlotte and nine-year-old Callie–have been invited to the Toneybee Institute to participate in a research experiment. They will live in an apartment on campus with Charlie, a young chimp abandoned by his mother. The Freemans were selected because they know sign language; they are supposed to teach it to Charlie and welcome him as a member of their family. But when Charlotte discovers the truth about the institute’s history of questionable studies, the secrets of the past invade the present in devious ways." — Algonquin Books.
