After twenty-five years of single-minded determination, Marianne Gordon has finally achieved her ambition and been promoted to Principal of the Vesper School for Zero-Gravity Artistic Display.

But her moment of triumph is cut short when she discovers that she must share her position with Josephine Knight, a celebrated zero-gravity performer who doesn’t know the first thing about teaching. Deeply insulted, Marianne does her best to carry on as though Jo isn’t there, but Jo has a way of making her presence felt.

When the future of Marianne’s beloved school is threatened, Jo may be the only person who can help – but only if Marianne can learn to let her in.
