See No Evil: 2

A dying Vietnamese physicist. A secret buried since 1972. And a technology that could make war disappear. When MIT professor Mai Tran travels to Hanoi to say goodbye to her grandfather, she never expects to leave with the blueprints for a device that can bend light itself. But someone else wants those blueprints too, and they aren't asking nicely. Enter Harmon Singer, ex-special ops warrior, part-time mercenary, full-time wiseass, and the last person you'd expect to be standing between the free world and a Russian hardliner with something to prove. With his girlfriend Aliz, a genius hacker named Ollie, and a pair of very capable Navy SEALs, Harm is about to take the fight from the back alleys of Hanoi to the streets of Brooklyn, from the mountains of Kyrgyzstan to the shadow of the most famous clock in the world. Invisibility is real. The threat is real. And somewhere in London, the countdown has already begun. You'll never see them coming...
