Harpercollins The Puppet Master.

He watches your every move
We’ve all experienced it. That creeping sensation of eyes on your back, the faint echo of footsteps following yours.

He controls you

He will make you pay
You think you’re in control of your own life? Think again. Because The Puppet Master is coming for you, and he won’t stop until you’re dead
