Voyage of the Dawn Treader

Voyage of the Dawn Treader begins during a holiday in the school year.  Peter has gone to study for an exam with Professor Kirke, and Susan has gone to America with their parents.  Edmund and Lucy must spend their holiday with their aunt and uncle, Alberta and Harold Scrubb, and their abominable cousin, Eustace Clarence Scrubb.  Eustace is the sort of mid who likes to pin dead insects to cards and to read books about fat foreign children doing excercises in schools.  He is a most disagreeable individual, and Edmund has to suppress the urge to hurt him every so often.  Lucy has more of a kind heart, but even she will get fed up with him.  In a back room in Eustace's house, there is a painting of a lovely little ship that looks incredibly Narnian.  Alberta put it way back there because it was a wedding present from someone she didn't want to offend.  Edmund and Lucy admire it every time they can get away from Eustace.  One day Eustace figures out where they go to get away, and decides to go bother them.  As he does so, the painting becomes more and more real, until Lucy can smell the salty wind from the sea, and Edmund can see the waves move.  This of course makes Eustace seasick.  Suddenly the painting either becomes so large or they become so small that they all are standing on the edge of the frame.  They then fall into the sea, and someone on the now-real ship jumps overboard to help them.  The three children and the other person are pulled back onto deck.  The person who helped them turns out to be Caspian, three years older, and this ship is Narnia's first ship built after the Telmarines conquered Narnia:  the Dawn Treader.
