Twin sisters Anjum and Baisan were born in an oasis of the great, beautiful, cruel Sahara Desert. However, baby Baysan is bought from a poor Arab family by French army officer Fernand Randel and his eccentric wife Françoise to raise her as their own daughter. Although the girls grow up in different conditions, they are connected by an invisible thread. The life of a French colony, what Algeria was like in the 19th century, the life of the Bedouins, ruthlessness and humanity, the thirst for justice and love in spite of everything - in the new adventure novel by Laura Beckitt.
