Tasha got kidnapped by some rogue demigods still fighting against the gods...
She escaped...
But this is what she looked like when she got back to Camp Half-blood...

Her shirt was an olive green when she was kidnapped... and the blood isn't hers...
Mostly.

The moral of the story?
Never mess with a demigod who's fatal flaw is anger.
It may just be the last thing you do...
