What if the deadliest threat to humanity didn't arrive with explosions... but with a simple cold?
When an ordinary student collapses during an exam, no one imagines it is the beginning of a global nightmare. As unexplained deaths multiply across continents, governments race against time, scientists search for impossible answers, and civilization begins to unravel.
In a world where every breath could be your last, survival is no longer a matter of strength. It is a matter of trust.
Because the final refuge may not be a place... but the last hope of humanity.
