The Complicated Calculus (and Cows) of Carl Paulsen follows fifteen-year-old Carl as he confronts his crush on Andy Olnan, a handsome and confident "city boy" recently transplanted to farm life from Minneapolis who may or may not share the same feelings. At the same time, Carl and his father clash over the future of their small and struggling dairy farm, a legacy of Carl's late mother: how do they honor her dream for the family while also ensuring financial security? Carl discovers his own resilience in the face of grief, adult-sized decisions, and unrequited love, and along the way learns to cope with both the challenges and rewards of being different.
