One yellow April morning, a seventeen-year-old girl makes a trivial decision. But is it trivial? What she decides will set her life on one of three radically different paths. That morning is long past. Now she is forty-one. On one life path, she calls herself Ántonia. She’s barely survived the implosion of a lesbian Utopian commune, one built on an abandoned oil rig. On another path, she is Katherine, a physician. After the death of an old lover, she contacts the only woman who still haunts her: the deeply religious Amanda. On a third, she is Kitty. She’s been happily married for twenty-three years. Happily enough. Until she meets Faye. The parallel lines of their lives are about to converge.
