4 12 stars. My favorite of the Percy Jackson series. When Annabeth is assigned a quest to find Daedalus' workshop somewhere in the Labyrinth, she takes Percy, Tyson, and Grover along. Together, they must navigate the twisting deadly Labyrinth, arrive at Daedalus' workshop before Luke, and convince him to help them save the Camp and prevent Kronos from becoming even more powerful than he already is. Battle of the Labyrinth was the most exciting and action fill yet. Loved it! This one is leading up to the final battle between the demi-gods and Kronos in the final Percy Jackson book, "The Last Olympian."
