That was an AWESOME sequel. Great follow-up. Percy's humor just continues to make me fall in love with him, and his adventures never fail to bore me! And my favorite character in this book was probably Tyson, hands-down. A little sad how his story ended, but that cliffhanger? FANTASTIC JOB, MR. RIORDAN.
(So I've read the PJ series before, but I barely remember any of this. Was it really this good?)
