Day Zero: Savage North Beginnings - Savage North Chronicles, #0

This prequel can be read at any point throughout the series. Survival of the fittest. Those four words accompanied me into the inferno. Followed by four others. I am the weak. And knowing I deserved far worse than death, I let the fire inside me burn. Before the fever, a deadly plan was set in motion from which a single text altered the world beyond remedy--three words that changed humanity forever.
It is time. After the Great Transformation, life in the North was miserable and bleak for those who remained. Loved ones were mourned. Survivors heard voices and could do impossibly unnatural things. Yet, amidst the fear and uncertainty, the grief and despair, Bert, Ross, Kat, and Cal found a semblance of hope. These are the stories of those who survived the beginning. Reading Order:The Darkest WinterThe Longest NightMidnight SunFading ShadowsUntamedUnbrokenDay Zero: Origin Stories
