Percy is twelve when he joins Camp Half-Blood, he’s confused, nervous, and completely out of place. His black hair is messy, his green eyes wide with worry, and he’s constantly on edge, unsure what’s real and what’s dangerous. He’s brave without meaning to be, loyal to his few friends, and starting to realize that the “trouble” that follows him everywhere might actually be the start of something bigger than he ever imagined. You were his best friend, or so he thought.
