In Sarah's house, the Bible and the Koran sit together on a shelf - two books bursting with stories... Sarah loves her two grandmas - Grandmother Azar and Grandmother Maria. Grandmother Azar tells Sarah stories from the Holy Koran, while Grandmother Maria tells her stories from the Bible. At Christmas time, Sarah snuggles in each of her grandmothers' laps and listens to two nativity stories about the birth of baby Jesus. They are the same in some ways, and different in others... But both can be Sarah's favourite.
