The Road to Damietta
The Newbury Award-winning author delivers “what may be his finest novel” in this young adult narrative of Saint Francis of Assisi and the Fifth Crusade (Publishers Weekly). Rich in the atmosphere of thirteenth-century Italy, The Road to Damietta offers a fascinating new perspective on the man who became Saint Francis of Assisi: the guileless, joyous man who praised the oneness of nature and sought to bring the world into harmony. Thirteen-year-old Ricca di Montanaro, who secretly loves the young Francis, watches in awe as he disavows his rich father and declares himself a servant of Christ. Following him on his journey, Ricca recounts Francis’s attempt to bring peace amidst the bloodshed of the Fifth Crusade. “Lord, make me an instrument of Thy peace,” he said. “Where there is hatred, let me sow love, where there is injury, pardon; where there is doubt, faith; where there is darkness, light; where there is sadness, joy.” And so he set off on the road to Damietta…
Are Dolphins Really Smart?
How intelligent are dolphins? Is their communication system really as complex as human language? And are they as friendly and peaceful as they are made out to be? The Western world has had an enduring love affair with dolphins since the early 1960s, with fanciful claims of their 'healing powers' and 'super intelligence'. Myths and pseudoscience abound on the subject. Justin Gregg weighs up the claims made about dolphin intelligence and separates scientific fact from fiction. He puts our knowledge about dolphin behaviour and intelligence into perspective, with comparisons to scientific studies of other animals, especially the crow family and great apes. He gives fascinating accounts of the challenges of testing what an animal with flippers and no facial expressions might be animal behaviour, Gregg challenges many of the widespread beliefs about dolphins, while also inspiring the reader with the remarkable abilities common to many of the less glamorized animals around us - such as chickens.
