Exodus is a science fiction novel written for teens to young adults by Julie Bertagna, published in August 2002. The story is set on an island faced with the problem of a rising sea level, caused by melting ice caps and other forms of global warming. Mara must think of a way to save herself, the other villagers and, most importantly, the world. The book was short-listed for the Whitbread Children's Book of the Year in 2002. Exodus is part of a trilogy; the sequel to the book is Zenith, published in 2007, followed by Aurora, published in 2011. Julie Bertagna was inspired to write this book in 1999, when she learned of two South Pacific Islands being engulfed by the sea as a result of global warming, forcing the people to find higher land. Bertagna started to investigate into the topic of global warming and the stories inspired her to write Exodus and its sequel Zenith. The purpose of the book is to inform young readers about global warming and convince them that something must be done about it. Source: Wikipedia (en)
