In this debut technothriller, cyber expert Tom Chatfield brings his hacker-hero Azi Bellow out of the shed where he dwells and into the real world, to help his online friend Sigma. Trying to expose a terrorist plot, she’s offended people in the darkest corner of the Dark Web, a site called Gomorrah. With questionable aid from some murky government spies, Azi and Sigma stumble into the real world and plenty of trouble in Berlin, then Greece, and finally Silicon Valley. A little over-the-top at the end, but Chatfield’s sly commentary is entertaining throughout. Read our full review here.
