Okay so, this guy is pretty much one of my favorite authors of all time. I love all of his books. He packs adventure, ancient mythology, and real life skills into one. Rick Riordan's books teach friendship, loyalty, and many other important qualities. I have read all of his books so many times-more than any other books. He has literally helped craft me to be the person I am today.
