You've read the book. You've seen the movie. Now submerge yourself into the thrilling, stunning, and action- packed graphic novel. Mythological monsters and the gods of Mount Olympus seem to be walking out of the pages of twelve- year- old Percy Jackson's textbooks and into his life. And worse, he's angered a few of them. Zeus's master lightning bolt has been stolen, and Percy is the prime suspect. Now, he and his friends have just ten days to find and return Zeus's stolen property and bring peace to a warring Mount Olympus.
