From Jennifer Szalai,Β The New York Times: βEngrossing. . . . Gellman [is] a thorough, exacting reporter . . . a marvelous narrator for this particular story, as he nimbly guides us through complex technical arcana and some stubborn ethical questions. . . . Dark Mirror would be simply pleasurable to read if the story it told didnβt also happen to be frighteningly real.β
