Deb Solomon jumps at the chance to go to work in another world: a university laboratory housing language-competent apes and the humans who study and care for them, led by brilliant primatologist Dr. Soraya Baldwin-Ruhl. But Soraya's star is already falling, and the lab's human inhabitants act increasingly apelike, even as the apes start to seem more human.
