Okay so I've been rereading Percy Jackson this semester (I'm gonna try to get Last Olympian done before the end of the year) and, while the first one really held up for me, 2 and 3 were kind of...let downs? And so I had been worried that the whole series wasn't going to be nostalgic and fun, but instead just disappointing. Thank the gods for The Battle of the Labyrinth, which shot the series back up into iconic.
