From the #1 Amazon bestselling Brewster Protocol series.

Everyone in this book is panicking about the end of the global economy. Except the dog. The dog is fine.
It starts with a rounding error. A currency rate that flickers to yesterday's number and back before anyone's coffee gets cold. By lunchtime it's happening in twelve banks across eight countries, and the global financial system is about to stop politely correcting itself and start coming apart on purpose.
Josh Brewster figures it out faster than most-mostly because the one person alive who understands the thing tearing through the world's money is sitting in his Singapore office, drinking his coffee, and is technically his client. Which is how a man who wanted nothing more than a balcony herb garden and a dog that respects boundaries ends up on a plane to mainland China, calling in a favor from someone who could buy a small country.
The instincts came back the moment he needed them. So did the people who shoot at him, the agencies that started this mess and now want him to mop it up, and a body that has firm opinions about being thrown down stairs at his age. He's got a CIA officer who's better in a firefight than he is, a former Soviet system engineered never to switch off, and exactly one good shirt.
The Typhon Protocol is the second Brewster thriller: a smart, fast-paced spy story with dry humor, global stakes, and a hero questioning every life decision that led him here. New mission. Worse odds. Same suit.
