Rick Riordan’s book The Last Olympian deals with a number of significant themes, including the following:
- Courage: Courage is required by many characters in the novel, especially the young hero Percy Jackson. Thus, at one point Paul says to Sally (Percy’s mother),
. . . it sounds to me . . . it sounds like Percy is doing something noble. I wish I had that much courage.
- Physical bravery, as when Zeus commends Tyson for his bravery in war.
- Evil, a trait frequently illustrated by Kronos.
- Luck, since many characters frequently wish each other good luck.
- Death, a theme mentioned constantly throughout the book.
- War, a major focus of much of the novel, which consists of one battle after another. At one memorable point, for instance, when Percy’s mother asks what he will do next, her son replies,
“I go to war. . . . Me against Kronos. And only one of us will survive.”
- Virtue versus Vice, as in the quotation just cited, in which Percy represents virtue and Kronos represents vice.
All the themes just mentioned are highly appropriate to a novel that describe the battle to save all that is good and just from all that is evil and vicious.
