I bought this book at the same time I bought the second and third books in the series, it just took me a while to get into it.
I'd read a few comments from people saying that this book is their favourite in the series but I still think that Sea of Monsters is my favourite so far. When I was reading this book I kept forgetting what their goal actually was and what their quest was actually about other than just getting caught up in different fights in the labyrinth. My favourite character in this book was Dionysius, I think that he is always hilarious and lightens up the tense situations and I liked seeing a bit of his character depth in this book when one of his sons died. I also really like Rachel Elizabeth Dare and think she'll play abigger role in the last book in the series when I get around to reading it. I would recommend this series to anyone who likes greek mythology and adventure stories.
Percy and Annabeth learn that Luke is planning to use Daedalus' labyrinth to invade Camp Half Blood to kill all the heroes so Kronos has no opposition when he comes to power. Annabeth gets to lead a quest into the labyrinth and she takes Percy, Tyson and Grover with her. They eventually learn that they need mortal eyes to navigate the maze and get them to Daedalus' workshop so Percy gets Rachel Elizabeth Dare, who can see through the mist, to help them. Once they find Daedalus they learn that he has already struck a bargain with Luke and Kronos and given them Ariadne's string however as he is telling them this some of Luke's army come in and attack Daedalus, betraying him. Percy, Annabeth, Tyson and Grover return to Camp Half Blood to help defend against Luke's army, but not before Percy discovers that Kronos has taken Luke's body to control. A battle then ensues at camp, which ends with Daedalus coming in to help the half bloods against Luke's army and saving the camp. He then dies so the labyrinth will die with him and everyone returns home for the summer.
