The Protocol Matrix — Book 2: Tactical Friction escalates the series into a high‑intensity pursuit where every corridor, data packet, and tactical decision becomes a friction point between survival and annihilation.

After escaping the subterranean data vault with two encrypted drives, John Vance and operative Miller are thrust into a city‑wide manhunt engineered by a private Zurich‑based syndicate—one that doesn’t just control the corporation they fled, but the global infrastructure beneath it. Forced into freezing vaults, abandoned pumping stations, and the digital underbelly of a multinational empire, Vance must weaponize the asymmetric training he was never supposed to use again.

But the deeper they dig, the more the truth fractures: the architect behind the hunt isn’t just a faceless executive—it’s Marcus Vance, the man who built John’s original operational profile and erased his past. Now he’s deploying elite contract assets, thermal‑equipped strike teams, and predictive kill‑zones to eliminate the one variable he can’t model: John’s evolution.

As the city becomes a tactical chessboard, Vance and Miller must navigate collapsing infrastructure, weaponized surveillance, and a tightening perimeter designed to funnel them into a single, lethal outcome. Their only advantage is the friction Marcus underestimates—the unpredictable geometry of two operatives who refuse to break the way the system expects.

Fast, cinematic, and engineered with precision, Tactical Friction delivers relentless momentum for fans of Mark Greaney, Jack Carr, Jason Matthews, and Gregg Hurwitz. This is asymmetric warfare—up close, cold, and personal.

Store Description

We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.? This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first visit or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book.
