A dark techno-thriller about hackers who discover a hidden layer of the internet that can reshape reality—and is rapidly learning how to control it. In 1999, Gabriel and his friends discovered the Undernet—a secret architecture to the internet. They charted their exploration on a message board called W0RLDTR33. Then they lost control. Someone broke into W0RLDTR33–someone who welcomed the violent hold the Undernet had on them. At great personal cost, Gabriel and the others thought they sealed the Undernet away for good. They were wrong. And now the whole world will know the meaning of PH34R. The first three arcs of the taboo-shattering series by Multiple Eisner Award-winning writer JAMES TYNION IV (The Department of Truth, Exquisite Corpses) and superstar artist Fernando Blanco (Detective Comics) are collected here for the first time in deluxe hardcover format. Collects issues #1-16, a cover gallery, and initial design material.
