He’s spent his whole life knowing everything.

Every variable. Every angle. Every threat he could calculate faster than most people could blink. Lincoln Bollinger built two fortunes before thirty, mastered the dark web, and designed systems that made governments nervous. 

But the one thing he couldn’t solve?

People.
Emotions. 
Her.

Mercury—the brilliant stranger he’s traded secret coded messages with for two years—vanished months ago. The quiet mind hidden inside poetry and algorithms was suddenly gone… until she sent him a desperate SOS encoded inside Emily Dickinson. A message only he could read. 

Rescuing her is easy.
Surviving what comes next won’t be.

The trafficking ring wants her silenced. Corrupt officials want her erased. And the only person she trusts is a man who barely knows how to hold a conversation without someone telling him to use his “inside voice.” 

But with Mercury beside him—quoting poetry when she’s scared, reorganizing his library when she’s overwhelmed, matching his brilliance with her own—Lincoln finds himself facing something he’s never been able to compute.

A woman who sees him.
A woman he’ll burn the world to protect.

And an enemy closing in fast.
