When someone slips a flash drive into Dave Shoemaker’s pocket at a rave, he dares to dream that his prayers have been answered. Dave was just a child when he discovered he could escape his abusive home life through immersion in his favorite video game. As a young adult, he’s become obsessed with a rumor about a secret cabal of hackers known as the Black Flock—gatekeepers of the most secret door in cyberspace. Dave wants access to the digital utopia they’ve allegedly built, and he will risk anything to get it. But when he realizes they’re hacking more than computers, it may be too late to quit the game.
