Dear Mr. Riordan,
Thank you so much for your books! Not only are they fun to read, but they also teach valuable information about the Greeks. I didn't realize this until yesterday, when I was taking a test on Greek mythology at school. One of the questions was, "Who killed Medusa?" I couldn't remember, and spent 15 minutes on that question before realizing that in The Lightning Thief, Percy kills Medusa! I know that Percy's based on Perseus, so that's who I wrote down, and I got it right! Thank you again.
