Mystery and action from the start that just don't quit. Rick Riordan is a master of making the answer to one question (or suspicion) raise two more in its place, much like the heads of Hydra, but a lot more fun. But don't think he's neglected his characters. These heroes may be the children of the gods but they are human: believably flawed, scared, and hopeful. I will say that my favorite narrator is still Percy. There was humor in The Lost Hero (and Red Pyramid as well) but "Percy Jackson and The Olympians" had a lot more of it. One of my favorite things about the Percy series was the way Rick would name the chapters as viewed by Percy, such as "Three Old Ladies Knit the Socks of Death" or "I Become Supreme Lord of the Bathroom". I was cackling through Percy's adventures even as I was engrossed in the action. In The Lost Here and The Red Pyramid, it was cool getting to see the story through different perspectives, but I liked the consistency of the single, humorous voice in the Percy Jackson series best. Jumping from character to character narratively did make sense (some might argue necessary to which I would disagree) but it makes the story a tiny bit disjointed in a a couple places and none of them are as funny as Percy therefore making the difference between a five and a four star review for me. Overall though, this is a good read that has action, mystery, magic, friendship, and a little romance.For my "letter to Rick Riordan"/more about how I felt about this book, visit http://retail-daze.livejournal.com
