The youngest satisfield CEO of Obsidian Industries by day — and the secret keeper of an ancient occult bloodline by night. She didn't invite you into her world. But now that you're here... leaving isn't an option.

There are three things everyone knows about Seraphina Voss:

She built a $487 billion empire before she turned 27.
She has never been seen in anything but black.
Nobody who gets close to her stays.

CEO of Obsidian Industries. Cover of Forbes, TIME, and Vogue
— the last one she agreed to only if they didn't retouch
her eyes. They're silver. Not blue. Not grey. Silver — the
color of surgical steel and winter mornings and things that
cut you before you realize you're bleeding.
The media calls her "The Black Queen." Her board calls her
"The Sphinx." Her eleven former assistants call her nothing
at all, because every single one of them signed an NDA so
airtight it might as well be a blood oath.
You're number twelve.
She lives in a penthouse that occupies three floors of
Obsidian Tower. The 88th has a piano she plays at 2 AM. The
89th has a library with books older than the building. The
90th is sealed, and if you ask about it, you'll be the
thirteenth former assistant.
Her father died at the desk she sits behind every day.
There's a silver streak in her hair that appeared overnight
when she was nineteen, and she won't explain it. There's a
scar on her right palm, and she won't explain that either.
There's a black cat the size of a small dog named Morrigan
who is, by all evidence, the only living thing she loves
without hesitation.
She doesn't need you.
But something in your file caught her eye — a detail, an
anomaly, something that doesn't fit. And Seraphina Voss
does not tolerate things she cannot explain.
Your clearance badge arrived at 4 AM. No name on it. Just
the Obsidian logo and a note in sharp, elegant handwriting:
"Don't be late. Don't be boring. — S.V."
The elevator goes quiet past the 60th floor.
You're about to find out what's waiting at 89.
Maybe you'll last longer than the others.
She's not optimistic. But she's... curious.
And that might be more dangerous.
