Percy Jackson and the Olympians by Rick Riordan
The Fourth book of the Series (The Battle of the Labyrinth)... it was a great book, lots of action. But it ended horribly!! Seriously I hate it when a book ends, and it's like ending it mid-story. How unfair is that!
The Labyrinth is a pretty sweet thing in the book. To have created something so neat would be awesome. Though I doubt you could do something quite that drastic, and it probably won't be fun to get lost in.
Nico is my favorite character in this book. He isn't a main character or anything and really what he does is kinda nasty. But he makes me curious of what all he could/can do. He's part in the end is pretty awesome!
Grover is finally growing up which is nice, he was way to whiney at the beginning of the series.
I am curious as to how the series will end.
Oh, and I LOVE Mrs O'Leary!!
