It has been twenty years since Sam Pinski, a young novelist, has spent the Fourth of July weekend with her family at their cabin on the Susquehanna River. There, she must confront a chaotic history of mental illness, alcoholism, and physical violence, and struggle to find perspective in the pulse of things familiar and respite from the shame of the taboo relationship that courses through her. As she does, a subplot emerges: Excerpts are included from Sam's metaphoric novel in which a pregnant man tries to solve the mystery of his fertility and absolve himself of his past. Then tragedy strikes the Pinskis and they must draw together, tentatively realizing that they will continue to spin off in their own orbits unless they begin the hard work of forgiveness themselves.
