What if the ending to the series is twelve-year old Percy living with Gabe after his mother died and all of his adventures were elaborate fantasies he came up with to cope with his mother’s death and his abusive step father?
Let this sink in for a moment- In all the books, never ONCE has Percy cried. Sure, he’s gotten teary-eyed, but he’s never full on cried. But I bet House of Hades will change that.
