The Codex File - If You're Online, You're a Target oleh Miles Etherton

Michael Robertson’s family has been murdered to protect the covert government project linked to establishing a new internet. Piecing together what happened leads him to four computer hackers, vehemently opposed to the new network, who provide the only means to hunt down the killers. But uncovering the truth leads to industrial espionage and a plot that leads right to the heart of government as he seeks the truth behind the Codex file.
