Justin C. Key's "The Perfection of Theresa Watkins" is a skillful speculative exploration of the intersection of race, mental illness, and the American prison system. Darius and Theresa Watkins confronted death once as fellow cancer survivors. Their lives are full and productive, their love a shield against Darius's bouts of anxiety and Theresa's occasional flare-ups. Yet when tragedy strikes, Darius will try everything to save his wife...even against his fears that she may have transformed into an entirely different person—literally.
