From the winner of the PEN/Malamud Award and “one of our most gifted writers” (Chicago Tribune) comes a comic novel about a divorced Midwestern dad who takes a cutting-edge medical test and learns that he has a predisposition to murder. In this fresh take on love and trouble in America, Brock Hobson, an insurance salesman and Sunday-school teacher, finds his equilibrium disturbed by the results of a predictive blood test. Baxter, a master storyteller, brings us a gradually building rollercoaster narrative, and a protagonist who is impertinent, searching, and hilariously relatable. From his good-as-gold, gentle girlfriend to the excessively macho subcontractor guy his ex-wife left him for, not to mention his well-raised teenage kids, now exploring sex and sexuality, the secondary characters in Brock's life all contribute meaningfully to the drama, as increasing challenges to his sense of self and purpose crash over him. The final battle—no spoilers, but there is one—couldn't be more delightful, as this quick and bracing novel reminds us to choose the best people to love, accept the ones we love even if we didn’t choose them, and love them all well.
