Alien InstinctA Post-Apocalyptic Romance

Apocalypse #2 / 2
by Cara Bristol
Alien Instinct: A Post-Apocalyptic Romance (Apocalypse #2) by Cara Bristol
Unrated
In a world where trust can be deadly, they’ll cross enemy lines to find love

Months after aliens from planet Progg-Res invade Earth, Chloe Thorne has yet to encounter another human being. Haunted by loss, but driven by grit, she wanders city to city in search of survivors.

One night, she camps in a rundown trailer in a remote area. Upon awakening, she finds herself face-to-face with an armed alien. She expects to be vaporized, but he offers her a deal: help him find his brother, and he’ll grant her freedom. She would rather die than assist one of the murderous invaders, but she’s counting on having a chance to escape.

Rok is a disgraced Progg soldier, alone and stranded on an unfamiliar world after a virulent plague wipes out his unit. When he finds Chloe, duty demands that he eliminate her, but something about her causes him to hesitate. Breaking all the rules, he coerces her assistance to locate his estranged brother, an important officer who may know what happened to the Progg forces.

From an uneasy alliance fraught with distrust, anger, and fear, each comes to see the other in an unexpected light. Chloe, fierce and stubborn, realizes the Progg soldier is nothing like the monsters who massacred her people, and for Rok, the very human Chloe awakens some very alien instincts.

On an Earth now divided by violence and vengeance, they’ll have to decide if they’re willing to risk a relationship or allow love to become the casualty in the fight for survival.

Also known as Survival Instinct Book 2.
