The Olympians #4: The Battle of the Labyrinth by Rick Riordan

My name is Annabeth, and Kronos's armies are trying to find a way to attack Camp Half-Blood using Daedalus's Labyrinth. Most people would get lost and die in the magical maze, but Luke thinks he can make the creator guide him through it using Ariadne's string. Percy thinks we need to kill Luke, but I know there is still some good inside him. I can't believe Luke is totally under Kronos's power, but I admit he's done some horrible things. He has a special hatred for Percy and has sent his minions to capture, or kill, him more than once. We've met up with Nico, and we aren't sure what he's thinking. He still blames Percy for Bianca's death and is being influenced by a ghost from the underworld. Nico has no idea the danger he will be in if Kronos or Luke realize he's a son of Hades. With Grover lost in the Labyrinth looking for Pan, I don't know how our quest to find Daedalus first can succeed. 

I've recently been reading many of Riordan's books from different series, and I feel like my reactions to them are very similar. The characters and cultures change, but the conflicts between the gods remain the same. Percy is still trying to figure out his relationship with Annabeth, but the issues with Luke complicate the problem. In addition, Nico has been motivated by his anger toward Percy, so Percy isn't sure how to deal with him. He wants to trust Nico, but his companions don't always feel the same way. This book adds an ecological twist with Grover's search for Pan and presents a commentary on our society. Grover and the other characters conclude we must all join together in order to save nature. This book continues the overall conflict in the series where Kronos is plotting to return and overthrow Olympus. You almost need to read the next book, The Last Olympian, to discover how it all turns out. Hint... if you've read Riordan's other series, it's highly likely that Percy and his friends will prevail!
