Prologue

"The saddest thing about betrayal is that it never comes from your enemies."

Percy Jackson, Jason Grace, Sadie Kane and Magnus Chase have few things in common between them. But, something links them all together. Betrayal. And they will have their revenge.

Okay, apart from that, this is my first fanfic, so please give your suggestions to improve! If you have any suggestions PLEASE put them in the comments, any and all suggestions will be considered!
