I just read the first book in The Heroes of Olympus, The Lost Hero. For you Percy Jackson fans out there, here's what's new and what's old:
1. Some kids are born from the Latin counterparts of the Greek gods. These kids don't have the ADHD and dyslexia handicaps.
2. Three new heroes: Piper (daughter of Aphrodite, can do charmspeak, which is like a Jedi mind trick), Leo (son of Hephaestus. Can create fire), and Jason (son of Jupiter, not Zeus. [spoiler]Oh, and Hera is actually helping him out because he's named after Jason. And he's got amnesia, thanks to Hera.[/spoiler]
3. New Big Bad.
1. Percy is missing. Annabeth is looking for him.
2. Chiron's running the camp now.
