The world’s banks have adopted a new technology called blockchain. But is it safe? To be sure, they hire cybersecurity super-sleuth Frank Adversego. Soon, he’s faced with massive hacker attacks, a crisis between Russia and the US, and an unstable genius bent on overthrowing global governments 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.

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.
