Against All Silence — E.C. Myers

After being a key figure in the exposing of government corruption, Max Stein has spent a quiet semester abroad in Paris, studying, staying off the Internet, and looking for his long-lost mother. But just as he is about to fly back to the United States for the holidays, trouble manages to find him once again.

Max receives a call from Penny, his on-again-off-again girlfriend who is part of the expert hacking duo DoubleThink. She wants him to meet with Ada Kiesler, a high-profile whistleblower hiding out at a foreign embassy in Berlin. Max has no interest in getting drawn into another corporate conspiracy. But when airport security suddenly detains him on suspicion of cyber-terrorism, he has little choice but to get involved. Soon Max and Penny are tangling with a new group of shadowy figures who are determined to control how the world shares its information. And some figures from Max's past resurface, including his own mother, whose life has mirrored his own in more ways than he'd realized.

In this action-packed follow up to The Silence of Six, Max and his hacker friends must fight to expose a corrupt corporation that has been systematically taking control of the Internet.
