A young white woman of Irish heritage who attends Gonzaga University in Spokane with Junior Polatkin. The two of them have a one-night stand while both living in the dorms over Christmas break; their affair results in a pregnancy, and Lynn fathers a child named Sean Casey. Her parents “refuse to accept Sean Casey’s Indian blood,” but Lynn “continually” reminds Sean of his heritage by reading him books about Indians. Lynn and Junior remain in touch, and Lynn ensures that Junior is able to talk to his son on the phone after he decides to quit school and return to the reservation.
