Summary
Juliet Montgomery was supposed to be building a career, not stealing classified information from a corporation tied to organized crime.
Now she’s being hunted through the streets of New York by men in black masks, hiding evidence, and taking refuge in the city’s underground.
Which would be terrifying enough on its own.
Unfortunately, the mysterious voice in the sewers she keeps returning to belongs to a mutant turtle with swords, too many secrets, and a habit of showing up every time she’s in danger.
Or:
Jules accidentally falls into the sewers while fleeing armed men.
Leonardo accidentally lets a stranger become the center of his universe.
Neither of them are handling it particularly well.

Summary
This mini-series is a companion to my original story, Into the Underground.
These chapters explore moments that happened between chapters, behind closed doors, or just outside the main storyline. While I loved these scenes and ideas, they didn't always fit naturally into the pacing of the larger story. Rather than leave them unwritten, I decided to give them a place of their own.
Think of this as a deeper look into the main story —the conversations, memories, and moments you didn't get to see the first time around.
I hope you enjoy going a little further underground with me.
