The Paternity Test by Michael Lowenthal
Pat Faunce yearns for more than his carefree New York life and his open relationship with Stu, an airline pilot. Above all, he wants to be a father. He persuades a reluctant Stu to move to Cape Cod, where they enlist Debora, a charismatic Brazilian immigrant, as a surrogate mother. But the men's attempt to have a child creates new emotional complications—with Stu's parents and sister, with Debora and her husband, and with each other. Building to a harrowing conclusion, this fearless, darkly funny novel asks whether making a new family is worth risking the one you have.
