Always an Angel, Never a God

What if Nico di Angelo wasn't saved in time?
...
No, I'm not saying that he died or snapped. I'm saying, what if at ten years old he was taken by Dr Thorne? Trained with Luke, the best swordsman of his generation? Started hating the gods like Luke, changed into a ruthless killing machine?

TW: Percico- I'm sorry, I had to add it in. However, this is going to be ruthlessly honest Percico- Nico going through his internalised homophobia, boundaries, stuff like that. They might break up horribly- it is a possibility, and truthfully very likely, if it actually happened. I'll just have to wait and see.
Non-graphic descriptions of violence, emotional manipulation, internalised homophobia, a few instances of strong language- but not many, I promise. If you get triggered by that, DO NOT READ.
This book does NOT contain: Slurs of any kind or any sexual scenes whatsoever.
I modelled this book so things in it happen realistically- it may not be happy, but it is what it is. If you don't like that, DO NOT READ.
Also... Valgrace. I'm sorry, I love it, it had to happen.
One more thing- to make the Percico less icky, I made Nico 2 years older- so 14 when Percy is turning 16, etc.
