Sunfish and Moonlight are two big-hearted sea creatures who love each other and who want to have a family. But the water where they live is too warm and they cannot spawn their babies. They decide to leave their home and go on an extraordinary adventure to a place where the water is colder. Straight from the tales told by Sunfish's mother, the North Star becomes their compass on a journey where they not only fight with hostile fish but escape from humans hunting them from big ships. Despite ongoing concerns about the seas' rising temperatures, they avoid all dangers and eventually spawn a family of many babies. Explaining global climate change to young children is by far one of the most challenging tasks an adult can face. A contemporary fable of love and adventure for young children, Sunfish and Moonlight creates awareness of global warming and its effects on the environment.
