内容简介：
Growing up in 1970s Wisconsin, Carolyn Hermann dreams of becoming a special-education teacher. But she has no idea how demanding her chosen vocation will be until she begins her first job: teaching autistic children in Midlands, South Carolina. Carolyn's class contains five high-functioning little boys, one of whom, Casey Ross, captures her imagination. Convinced that he is emotionally disturbed rather than autistic--partly because she believes his mother is remote and uncaring--Carolyn fantasizes about curing Casey even though her program director supports the diagnosis of autism. The following year Carolyn is assigned to teach a class of severely disabled students. Dealing with them is an enormous challenge, and she misses Casey. Burned out after two difficult years, Carolyn leaves teaching to become a homemaker and mother. Yet, despite the fulfillment she finds in this role, she feels like a failure for abandoning her students. Many years later Carolyn has returned to teaching and attends a convention where she encounters Casey's mother, now a disability-rights attorney. The two women reconnect and find that they have a great deal in common. And finally, their reunion provides the answer to a question that's haunted Carolyn for decades: Whatever happened to Casey Ross?
