Rick has the habit of making most of his series sound the same. Percy Jackson was pretty good though. I'll definitely be reading the rest of the series. Percy is quick witted and likable, and Annabeth is so badass, but Grover is definitely my favorite character. I look forward to reading the rest of the series.
ADDITIONAL: gods bless Rick for the subtle suggestion that kids with dyslexia and ADHD are all demigods.
