Narnia has got a new enemy. One year has passed in our world while hundreds have passed in Narnia. Peter, Susan, Edmond and Lucy are about to board trains to boarding school when they find themselves going into Narnia. Telmarines from another country have invaded Narnia. Prince Caspian was a Telmarine, but he fights to save Old Narnia. Old Narnia stands for the native Narnians, like dwarves, and talking beasts. The Narnians were losing the war before Peter and the others came. Peter, Susan, Edmond, and Lucy help Prince Caspian win the war against the Telmarines.
My favorite part was when Peter defeated the king of the Telmarines. I would recommend this book to anyone who likes fantasy and adventure combined.
