Where Flynne and her brother, Burton, live, jobs outside the drug business are rare. Fortunately, Burton has his veteran’s benefits, and he finds a new job: beta-testing part of a new game, he tells her. It seems to be simple: work a perimeter around the image of a tower building. Little buglike things turn up. He’s supposed to get in their way and edge them back. He’s offering Flynne a good price to take over for him. What she sees, though, isn’t what Burton told her to expect. It might be a game, but it could also be murder.
