Best part of story, including ending:
I didn't like that the book was in 3rd person. You couldn't really know everyone's feelings and thoughts in depth.
Best scene in story:
When they found Percy and the Romans Camp Half-Blood. I liked it because it's like finding life in a different planet. They had found people they could become friends with or enemies.
Opinion about the main character:
I liked Leo because he brought the most humor to the book.
