These books keep getting more awesome. Goodreads needs to start offering more than five stars. In this book, Percy and his friends have to find the creator of the Labyrinth to stop Kronos from overthrowing the gods.

This book is darker than the previous ones, and I have a feeling that the next one is going to be even darker. I'm enjoying watching Percy grow up as the series progresses. He's getting smarter. Maybe not about girls, but he's getting smarter about life. He's becoming a confident leader with a very funny self-deprecating sense of humor. 

Besides Percy, my favorite character in this book was Nico, even though he seems much, much older than his age. At times, this series is very predictable, but I have no idea what's going to happen with Nico. He's an interesting anti-hero. I want to read the next book just to find out what he does.

This book wasn't as funny as the others, but that was okay with me. The fast-paced plot and the tension were enough to keep me interested. Like the other books in the series, this one had noticeable typos and editing mistakes.

I'm ready for the last book. I know that it won't disappoint.
