Robert Ludlum's The Utopia Experiment

The Merge: a device destined to revolutionise the world and make the personal computer and smart phone obsolete. When Covert-One's Jon Smith is assigned to assess its military potential he discovers that its enhanced vision, real-time battlefield displays, unbreakable security, and near-perfect marksmanship could change the face of warfare for ever.
Meanwhile, CIA operative Randi Russell encounters an entire village of murdered Afghans - all equipped with enhanced Merge technology. As Smith and Russell investigate, they're blocked by someone who seems to have access to the highest levels of the military.
Is the Merge really as secure as its creator claims? And what is the Pentagon so desperate to hide? Smith and Russell are determined to learn the truth - but will they pay with their lives...?
