Book excerpt: The acclaimed writer/performer Lisa Kron's newest work is all about her Mom. It explores the dynamics of health, family and community with the story of her mother's extraordinary ability to heal a changing neighborhood, despite her inability to heal herself. In this solo show with other people in it, Kron asks the provocative question; Are we responsible for our own illness? But the answers she gets are much more complicated than she bargained for when the play spins dangerously out of control into riotously funny and unexpected territory.
