P.S. I got The Demigod Files from the library for fun (it's a collection of three short stories set in Percy's world taking place after The Battle of the Labyrinth). I don't usually go in for those supplemental things (since I get irritated when I feel like people are just trying to make more money off a good thing), but this one is worth it. It's Rick's writing, so it was fabulously well done. Also, I thought one of the stories in particular will play an important role in the final book. Oh, and who wouldn't want the bonus of reading the first chapter of the last book (also included at the end)?
