A year has passed since Ari gave birth to Walker, though it went so badly awry she has trouble calling it “birth” and still can't locate herself in her altered universe. When Mina, a one-time cult musician --- older, self-contained, alone and nine-months pregnant --- moves to town, Ari sees the possibility of a new friend, despite her unfortunate habit of generally mistrusting women. Soon they become comrades-in-arms, and the previously hostile terrain seems almost navigable.
