The world didn't end overnight. It unraveled in waves of horror.

First came the viral plague that wiped out a massive portion of humanity. Then, just months later, a coronal mass ejection crippled what remained—obliterating power grids, communications, and any hope of rebuilding. With the world plunged into darkness, survival became a matter of instinct.

Ayden McAllister was no stranger to pain. Scarred by trauma and the loss of her fiancé to the virus, she's learned the hard way to trust no one and keep moving. Formerly a wildlife biologist, now a hardened tracker, Ayden travels with one of the few people she still believes in—Master Chief Markus Hale, her late fiancé's best friend and protector by oath.

Their quiet survival is upended when they cross paths with five civilians being threatened by violent men. In an instant, the pair becomes a group of seven. But safety in numbers comes with its own dangers—especially when one of their own is kidnapped.

Determined to mount a rescue, Ayden and Markus encounter another band of survivors on a similar mission. As alliances form and suspicions rise, one question looms large: who can they trust in a world where trust can get you killed?

Romance blossoms. Tragedy strikes. Friendships are tested. And betrayal is inevitable.

Survivor's Instinct is a gritty, emotional journey through a post-apocalyptic wasteland where loyalty is rare, hope is fragile, and survival means facing both external threats and the demons within. When the world falls apart, the strongest instinct is to survive—but sometimes, survival demands more than just staying alive.
