Escaped

Sequel to The new avenger (but it's still understandable if you haven't read the first)
Nico was kidnaped, tortured and raped for two years in Tartarus. Which is a long shut down camp that's run by, you guessed it Tartarus, who kidnaps children.

When he escapes he stays with Percy and his husband Loki (Will and Peter too) as he recovers.
Lots of fluff and angst and Definitely solangelo.

Triggers
Self-harm
PTSD
All the good angsty stuff.
