Remember the fascinating story of the baby hippo who was rescued from the sea after the tsunami? He was taken to a sanctuary where he discovered a new mother, a 130-year-old giant tortoise. Two new children's books present this story in unique and heart warming ways. Owen and Mzee by Isabella Hatkoff is filled with fabulous photos of Owen as he wins over his unlikely companion. Jeanette Winter's picture book adaption Mama:a true story shows the harrowing journey through rich illustrations and a one word mantra that says it all - "Mama!"
