Logging Off by Caitlin McKenna

In 2095, every facet of society runs perfectly by computers and advanced technology. Citizens like Britannia Stone conduct their lives effortlessly with a genetically embedded barcode linked to Central, the world government. But this easy lifestyle, one without economical hardships, crime and disease, comes with a price - the freedom of choice. Now world citizens are beginning to mysteriously disappear. John Ettinger, a society inactive and member of the underground group called the Starters, knows the reason why. With the help of Kendall Knowlton, a highly-gifted psychic child, it becomes a race against time as Britannia and John join forces before they are next to disappear. They must stay alive long enough to reach Central's mainframe and destroy the enemy before the enemy destroys all of mankind.
