This, and many other exciting adventures are found in a book called, The Voyage of the Dawn Treader by C.S. Lewis. This book is about a young king named Caspian, who is trying to find seven lords that his evil uncle Miraz had sent out long ago to try and find the worlds end. Reepicheep is a talking mouse who is also trying to find the end of the world. Edmund, Lucy, and Eustace were pulled into Narnia through a picture in their own world. In the end, Caspian succeeds in finding all seven lords, and Reepicheep finds the utter east, where Aslan lives, and the children get home safely.
