Nour is a young Syrian girl who has lost her father to cancer. Wanting to be close to her relatives, Nour's mother - a cartographer who makes beautiful hand-painted maps - moves her family back to the city of Homs. Nour's father was a real storyteller and he told her that the roots of the trees connect to the ground across the world. She knows they left her father in the ground back in America, so she starts telling him the ancient fable of Rawiya, whispering it into the ground so he might hear. Rawiya left her home dressed as a boy in order to explore the world. She became apprenticed to Al Idrisi, who was a famous cartographer tasked by King Roger II of Sicily to make the first map of the world. Together with Al Idrisi, Rawiya travelled the globe, encountering adventures - including the mythical Roc and a battle in the Valley of Snakes - along the way. It is this story that gives Nour the courage to keep going when she has to leave Homs after it is bombed and faces a long journey as a refugee in search of a new home - a journey that closely mirrors that of Rawiya many centuries before. When Nour and her sister are forced to part from their mother, she gives them a special map that contains clues that will lead them to safety. The two stories are beautifully told and interwoven, the real interspersed with the magical/imagined so that the overall effect is uplifting - about the strength of the human spirit, the strength of women in particular, the power of a journey, and what it takes to find a home.
