Rosalyn Coleman Williams directs the production at Manhattan Theatre Source.

The work is billed as a "death-defying roller-coaster ride thinly disguised as a well-made play that capriciously pits two educated and otherwise beautiful women against each other in a heavy weight championship of the mind."

Craig T. Williams produces. The cast features Pennie Diamond Quintana (Abingdon Theatre Company's Nighthawks.), Yvette Ganier (U.S. and London productions of Jitney) and Ian White.

The ladies of the play are a therapist (Yvette Ganier) and her new, wounded client (Pennie Diamond Quintana). The latter, Cassie, attempts to punish and manipulate the therapist. Anger, grief and pain inform the client's experience.

Playwright Fragola has been working in the mental health field for over 15 years. She holds graduate degrees in both Social Work and Psychology, and "has long been interested in the therapeutic process and how the past affects the present." She wrote It Isn't the Moon over the past seven years "in her very spare time."

The creative team includes designers Tom Powers (scenery) and Anita Ellis (costumes).

Manhattan Theatre Source is at 177 MacDougal Street at Washington Square Park.

Tickets are $18. For more information, call (212) 868-4444 or visit www.smarttix.com.
