Blood Safe Zone

When the sky cracks open and the System brands humanity with levels, classes, and kill notifications, ex-paramedic Mara Vale survives the first monster wave by doing what she has always done: running toward screams. But the hospital she turns into a refuge becomes a glowing Safe Zone with a terrible rule—each dawn, it demands blood to keep its walls intact.

As corpse-eating wights flood the streets of Pittsburgh and survivors awaken brutal classes, Mara gains the rare Hemomancer path, healing others by spending her own life and weaponizing blood in ways that terrify even her allies. Rival factions rise from churches, police precincts, and corporate bunkers, all starving for resources, cores, and control of Safe Zones.

When Mara discovers the System is not saving Earth but cultivating it, every level becomes a chain. To protect her people, she must master the horror inside her class, bargain with monsters, and decide how many lives a sanctuary is worth.
