Six girls of thirteen and fourteen years old are taken from their bedrooms in the early hours, no forced entry, witnesses or forensic evidence. Their phones are left charging on their nightstands. Six girls across New York in forty-three days — and not one of their cases connected in any law enforcement database.

When Gloria Hanson begs for help finding her thirteen-year-old daughter Lonnie, Kira Cross and her newly formed KCBI team take on the case. Within hours Rebecca AI uncovers the true scale of what the authorities missed — twenty-two girls gone in twelve months, most filed as runaways, none of them linked, all of them taken by the same invisible operation.

The trail leads to Conrad Drayke — Yale-educated, Central Park South penthouse, a philanthropist who has donated six million dollars to a children's education charity. Underneath that, a network of invitation-only private clubs operating across New York, Miami, London, Dubai, and Singapore, with a membership list nobody is allowed to see.

And somewhere on the eastern seaboard, a cargo ship has loaded a container of human cargo bound for Amsterdam and set sail.

There are twenty-four girls in the container ship — Atrius — they are in stormy seas with a clock ticking to save them before they reach their destination thousands of miles away from New York City and being lost forever.

The truth doesn't hide in the shadows. It doesn't hide in plain sight. It hides in the Darkdown.
