Flashmob

In addition to being a gun for hire, John Smith has the ability to read minds. At the wedding of a reality-television celebrity, Smith witnesses a group of gunmen open fire. Though he's unarmed, Smith cripples one of the killers and is able to pry one word form his mind: "Downvote."

Hacking into the brain of an FBI agent, Smith discovers that the Bureau has been investigating a nefarious new threat called Downvote, an encrypted site on the Dark Net that lists the names of celebrities and offers a hefty bounty for anyone who can kill them - unleashing an anonymous, deadly flashmob with a keystroke.

After Smith traces a series of electronic signatures to a reclusive billionaire living at sea accompanied by a scary-smart female bodyguard, the hunt for his prey take shim from Hong Kong to Reykjavik to a luxury gambling resort deep in the Laotian jungle. But Downvote's creator realizes that the only way to stop Smith is to kill him . . . because there's no hiding from a man who can read minds.
