Three friends. Three houses. Three outsiders moving in. For these three teenage girls, "home" has become a battlefield. As their parents’ new “relationships and marriages” bring in stepmonsters and boyfriends who range from cold to calculating, the girls realize they are no longer the priority in their own lives. But they aren't victims—they’re witnesses. Bound by a pact of survival and a shared refusal to be erased, they navigate the treachery of their new family trees. Stepmothers is a sharp, unflinching look at what happens when the people meant to protect you look the other way—and the friends who step in to fill the gap.
