Has anyone else read any other Rick Riordan books, other than the Percy Jackson ones? I just finished reading The Red Pyramid (book 1 of the Kane Chronicles) and I have to say, I'm rather impressed with it. I can't imagine how much research Riordan must of done to do the Jackson books and now the Kan Chronicles.<br/><br/>He does make cross references to his Percy Jackson books in it.<br/><br/>Examples:<br/><br/>* Towards the beginning of the book Amos states that Manhattan has its own set of gods and that they must be kept separate from Egyptian gods. He says this while looking at The Empire State Building, the current home to Mount Olympus.<br/>* Later in the book, Thoth mentions that the Greeks would confuse him with Hermes, something he takes offense to as Hermes is apparently of a very different character.
