To me, Rick Riordan is the most amazing writer that ever lived! His main characters are so loveable, and his enemies are some of the most hated beings in my mind. To be a good writer, you need good characters. Riordan definitely understands that. I love to write, so reading Riordan's books really encourages me to do my best and create the best characters possible.
My favorite book by him is The Lightning Thief. I've read books 1-3, and they're all amazing, but I don't think my favorite Rick Riordan book will ever change. One thing I particullarly like about his books are that each book is the next year in Percy's life. You get to watch Percy grow up, and see him turn from a 12 year-old boy, scared, upset, etc., to a 16 year-old hero, ready to save the world, no matter what it takes. I love Rick Riordan's writing style. It's absolutely amazing.
My favorite character has to be Percy, but Annabeth definitely falls second in line. I love their personalities. My friends and I have been trying to make a TV show based on the series, and I play Annabeth. I hope to make Annabeth come to life, and show people what I think of her.
Riordan said in an interview that he never intended The Lightning Thief to become a book. It was simply a bedtime story for his oldest son, who encouraged him to write it down. He did, and look at him now! I hope to be a writer like Rick Riordan some day. His books are so amazingly unique! There will never be a book better than any book that Rick Riordan has written, never a character more loveable than Percy Jackson, never an enemy more hateable than Luke Castellan, never a writer more amazing than Rick Riordan.
