Olympus, a secret agency ran by 'The Gods' for training good heroes at the age of sixteen years old.
Titan, another secret agency ran by 'The Titans' for training bad heroes to challenge Olympus at the age of sixteen.
Every year Titan takes one teen forcibly at the age of fifteen from Olympus, to brainwash and train them as their own.
This year, thirteen year old Nico di Angelo is taken, causing an uproar as he is nowhere near old enough to be taken. However, Nico is still kept and stowed away by Titan and he is not seen again.
That is, until he assassinates Percy Jackson, his old best friend, on a mission.
Seeing Nico again after nearly four years, with a blank stare and erased memory, sends Percy into a state of near delusion.
So, The Gods make Percy promise to himself that he will get Nico's memories back, and all will be well again. Olympus would reclaim a lost hero.
But is it ever that easy, reclaiming a trained killing machine's memories?
