Forty-something mother of two Josephine Cortes is at a crossroads. She has just moved to a posh new apartment in Paris after the success of the historical novel she ghostwrote for her sister, Iris. Still struggling with her divorce - the result of her husband running off to Kenya to start a crocodile farm with his mistress - she is now entangled in a lie orchestrated by her sister. And just when things seem as though they can't get any more complicated, people start turning up dead in her neighbourhood.
As Josephine struggles to find her voice and her confidence amid a messy web of relationships and a string of murders, she and those around her must learn to push on with determination, like headstrong little turtles learning to dance slowly in a world that's too violent and moving too fast.
