The banks hire cybersecurity super-sleuth Frank Adversego to oversee the project, and he's not so sure. Meanwhile, Russian troops are massing on the European and the Kremlin is using a financial blockchain of its own to make a joke out of Western economic sanctions.Soon, Adversego is faced with massive hacker attacks, a deepening crisis between East and West, and the machinations of an unstable blockchain genius bent on overthrowing global governments in order to create a brave, new, anarchist world.Andrew Updegrove brings a rare combination of drama, satire and technical accuracy to his writing. The result is a book you can't put down that tells you things you might wish you didn't know. Admiral James G. Stavridis, retired Commander, U.S. European Command and NATO Supreme Allied Commander Europe, and current Dean of the Fletcher School of Law and Diplomacy Andrew Updegrove's Frank Adversego thrillers are realistic page-turners, making it clear that if you're not worried about cybersecurity you're not paying attention.
