Back onto the Dance Floor by Annemarie Nikolaus

After sixteen years, Friederike Lagrange dares to return to the dance floor for the first time: A serious car accident had forced her to give up competition dancing. Instead, dance became her research topic and she made a career as a professor in history.
A colleague becomes her new partner because her husband George doesn‘t want to take part in a simple dance circle like a beginner: It would be beneath his dignity as chairman of the Lietzensee Dance Club. But he supports her when she wants to shoot a film about the dances of the Baroque with the square dancers and the Latin formation of the club. Then suddenly he wants to dance the Baroque dances with her himself.
Friederike is faced with a dilemma: Since the accident she has longed to be able to dance with her husband again one day. But she also doesn't want to disappoint her colleague. Can she find a way out that doesn't offend either of them?
