She lives in an institution, unlikely to ever leave. Art teacher Alison looks fine on the surface. But the surface is a lie. She's struggling to make ends meet and to forget the past. Meanwhile, someone is watching both Kitty and Alison. Someone who never forgot what happened that day. Someone who wants revenge. And only another life will do...Engrossing psychological suspense from British author Corry (My Husband's Wife, 2017).
