Re-emergence: Book One of the Surviving the Blaze series

When a mysterious fire scorches the earth and brings the population close to zero, Michael Nash finds himself alone in a world exploding with chaos, violence and lawlessness. His wife is gone, perhaps dead. His friends, family and neighbors have also disappeared, victims of random violence and stray animals that have mutated into savage beasts.
And the biggest threat of all: The Patrollers.
Patrollers are re-animated humans, handcrafted into unstoppable killing machines. Protected by steel armor and guided by the instructions of their makers, they're on a mission to wipe out the remaining traces of humanity. The only thing in their way is trained army sniper Michael Nash.
But will his sharpshooting skills be enough to save his wife and the rest of humanity?
Can Nash's rogue gang of ex-cons and vagrants bring down an army of killer robots?
