The Savant of Chelsea, by Suzanne Jenkins

The hero of this novel is a mentally ill woman; her illness manifests as savant expertise as a neurosurgeon and an inability to effectively communicate with or relate to others along with an inattentiveness to her personal health (i.e., nutrition).   She discovers that the baby that was taken from her as a child (due to abuse) lives and has children of her own.   In the process of caring for her grandchildren, she experiences a (remarkable) change in empathy and communications skills, essentially approaching functional social skills for the first time.

I give this book a C-.
