Jing and Gyp used to live a good life with their mother on the moon, but their father took them for a weekend visit and abandoned them on Earth in a dark arcade called Squirrels in Frankfurter Highlight, a 24-hour gamblers’ haven of vidmind games. Jing must save her brother from the arcade's ogre, Base, the security, who hunts the boy to trade him for cash to the cruit-joes who will sell him as cheap offworld labor. A bad gamble costs Gyp his consciousness; now his mind is lost and locked inside a Gamm, the arcade's gaming machines, where bleeders lurk. Gyp can only be saved by Jing, but she's never played a game in void link.
