what if Percy Jackson, Bianca and Nico Di Angelo got captured?

Basically exactly what the title says, though it might get a little dark. trigger warnings will be at the start of every chapter.
✨all characters will suffer!✨
don't expect much comfort
(also, this is at the beginning of Titan's curse) (Also it's a dead dove dont eat fanfic.)
All characters belong to Rick Riordan
The fanfic is the only thing I own not the characters
