Breach Protocol (en Inglés) - Edward Kress

The end of the world does not begin with a warning. It begins with a breach.

When a classified containment failure unleashes a fast-moving biological nightmare into Pittsburgh, the city collapses in hours. Streets become kill zones. Hospitals turn into slaughterhouses. Police lines break. Military response vanishes into confusion and blood. What first looks like a violent outbreak quickly becomes something worse-something engineered, something mutating, and something far beyond anyone's ability to control.

Adam Mercer is not a soldier, a scientist, or a hero. He is just a man trying to survive long enough to protect his daughter as the city around him is torn apart. But survival becomes more complicated when the infected stop behaving like ordinary monsters. They move faster. Hit harder. Adapt. Some are changing into something stronger, more organized, and more terrifying than the infected the world thought it understood. As entire neighborhoods burn and the dead flood the roads, Adam is forced into an alliance with hardened survivors, desperate civilians, and remnants of a collapsing response effort that may already know more about the outbreak than they are willing to admit.

As Pittsburgh turns into a graveyard of fire, smoke, and flesh, Adam begins uncovering the truth behind the breach itself. This was never just an accident. Somewhere beneath the collapse lies a buried experiment, a failed containment protocol, and the first signs that the infection is not simply spreading-it is evolving. Every hour the city survives, the threat becomes smarter, more violent, and harder to kill. And if Pittsburgh is only the beginning, then the rest of the country may already be standing on the edge of the same abyss.

Breach Protocol is a brutal post-apocalyptic horror thriller packed with outbreak terror, urban collapse, desperate survival, military failure, and the first horrifying steps in a much larger evolutionary nightmare. Dark, fast, and relentless, it launches a series where the infected are only the start of the problem. Because once the breach begins, containment is no longer the goal.
