Sea of Monsters

The book I'm currently reading is Rick Riordan's "Sea of Monsters."  

This book is the second in the series of Rick Riordan's "Percy and the Lightining Theif."

It is about Percy returing to summer camp for half bloods. (A half blood, is a child of one of the Gods, making the child half human, half God.) Percy's camp's magical borders have been poisioned, causing all the half bloods in the camp to be at risk for monsters. This is how far I have gotten in my book, I  will keep you posted when I read more.
