The throne of fire.
I am in the middle (or close to it) of the book the throne of fire. who has also writes the percy jackson and the Olympians books. so far sadie is telling the story. And carter has just been poisoned! sadie just got Set's Secret Name Erased out of her mind. the name was Evil Day. Sadie still knows it but she just doesn't remember how to say it the right way. So far it is a great book. I would recommend this book to others and the rest of the books.
