Product: Missing: A Private Novel When the CEO of a research company disappears without a trace, Private Investigations has to catch a brutal killer-a killer headed straight to the victim's door.
Craig Gisto has promised Eliza Moss that his elite team at Private Sydney will investigate the disappearance of her father. After all, as CEO of a high-profile research company, Eric Moss shouldn't be difficult to find.
Except it's not just the man who's gone missing. Despite the most advanced technology at their disposal, they find every trace of him has vanished too.
And they aren't the only ones on the hunt. Powerful figures want Moss to stay "lost," while others just as ruthlessly want him found.
Meanwhile, a routine background check becomes a frantic race to find a stolen baby and catch a brutal killer - a killer Private may well have sent straight to the victim's door . . .

Product: Unsolved (Invisible Book 2) In this follow-up to the #1 bestselling thriller Invisible, every perfect murder looks like an accident, but as bodies start to pile up across the country, two FBI agents realize that something horrible is happening.
FBI agent Emmy Dockery is absolutely relentless. She's young and driven, and her unique skill at seeing connections others miss has brought her an impressive string of arrests.
But a shocking new case -- unfolding across the country -- has left her utterly baffled.
The victims all appear to have died by accident, and have seemingly nothing in common. But this many deaths can't be coincidence. And the killer is somehow one step ahead of every move Dockery makes. How?
To FBI special agent Harrison "Books" Bookman, everyone in the FBI is a suspect -- particularly Emmy Dockery (the fact that she's his ex-fiancee doesn't make it easier).
But someone else is watching Dockery. Studying, learning, waiting. Until it's the perfect time to strike.
