Troubled times have come to Narnia as it is gripped by civil war. Prince Caspian is forced to blow The Great Horn of Narnia, summoning the help of past heroes, Peter, Susan, Edmund, and Lucy. Now they must overthrow Caspian's uncle, King Miraz, to restore peace to Narnia. Prince Caspian was the second book written by C.S. Lewis in the Chronicles of Narnia series, but it is considered to be the 4th in the series by those wishing to read the books in chronological, rather than publishing, order.
