Percy Jackson, a teenage demigod, is the son of Poseidon. He is on the lookout for Nico, who has no idea what he's gotten into, and who blames Percy for his sister's death. And, of course, on the lookout for Luke, who has been aiding the evil titan Kronos in his quest to destroy the gods, and who does not care if innocent people die in this quest. But even more problems come into view when an entrance to the Labyrinth (a maze that is quite capable of killing Percy and his friends) is found in the center of Camp Half-Blood. Percy, Annabeth, Grover, and Tyson must enter the maze and convince Daedalus to help them before Luke gets there first.
This book is just amazing. I loved the balance between action, humor, ( I even had to stop reading at some points, to show my family the excellent jokes) suspense, and mystery. The book, being based on Greek mythology, has lots and lots of references to the Greek gods and goddesses, myths, and some of the heroes. And yet, it manages to have a unique plot, despite all of the other stories inside it. Rick Riordan did an excellent job of this, and the book is just amazing. However, I would recommend reading the first books in the series before this one, as it is a continuation of that story. It was great, and an especially good read for people who are bored out of their minds, because it was long and filled with great writing.
