A Lost Friend (Percy x Silena)

after the gruesome death of Annabeth Chase, Percy's girlfriend, Hades comfort him by allowing him to bring back one person who died in the second Titan War. "Silena Beauregard" he said.

what will happen? Will they become friends? will they kill each other? only time will tell

all rights go to Rick Riordan, for the Percy Jackson characters, Me, for the plot, and J. K. Rowling, for Chocolate Frog cards, and Deathly Hallows... And Harry Potter... And I will make this after Ginny and Harry get married

Also I may use a few OCs here and there.
