The Loop (Paperback) (ISBN-13: 9781955747035)

A hacker on the run.

The most powerful AI ever built.

And a nuke aimed at a city.

Helen Chen had started to hope that she'd found peace.

After fleeing New York, she's settled in Hong Kong under a false name, found a job she loves, and even started to make new friends. But when an innocuous conversation makes her suspect her new boss, she can't resist her nature and starts digging for the truth. What she finds will change her life forever.

Mike Connelly is looking for war.

In New York, Mike Connelly grows weary of being a silent mole inside Engel's organization. Forced to take greater and greater risks by his handler, he is frustrated by the lack of results. He wants to resurrect the Unit. He wants action. But more than anything, he wants to bring the war to Engel's doorstep. But every war has a price.

The Loop is an edge-of-your-seat adventure that continues the Upgrade series and sets the stage for the final three books.
