Another delightful tale in the Chronicles of Narnia series. This one did not include Peter and Susan, but it did include the two younger children and their cousin, Eustace. The 3 children were in Eustace's bedroom when the picture on the wall came to life and they went sailing back to Narnia on the Dawn Treader.
They join Prince Caspian on his search for seven of his father's friends who were banned from the kingdom by his evil uncle. The children have many grand adventures.
One of my favorite parts is when Aslan helps Eustace painfully peel of the dragon skin. Eustace has to start the process himself, but he is unable to finish without Aslan's help. In fact, the greater part has to be done by Aslan. Very beautiful imagery and meaning.
