Book excerpt: Stories of twins are told with astonishing frequency in contemporary culture. Films and novels from recent decades repeatedly tell of the stranglehold of brotherly love, the evil twin who steals her sister's lover, the homicidal mutant twin, the reunion of twins separated at birth, warring twins, and confusion between look-alikes. Twins in Contemporary Literature and Culture asks why we keep telling twin tales and how these have been transformed in recent retellings to reflect the preoccupations of the times.
