This book made my life hard and I decided to rewrite it. ~~~~~~~~~~~~~~~~~~~~~~ It's over. Charon's gone back to his old job, everyone's alive, and it's over. Or is it? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The twins have conquered their biggest challenge yet: high school. Percy gets to go to college with Annabeth, and Aria gets to wander around with Reyna. Everyone's okay, right? But when SHIELD does a headcount of everyone on their watch list, and they can't find the twins, they send the Avengers after them. To make matters worse, the twins aren't as in sync as they used to be. Will they be okay, or have Percy and Aria lost each other, their built-in best friends, forever?
