The World Without Flags by Ben Lyle Bedard

Ten years after a plague of parasitic worms decimated humanity, turning some of them into zombies, the world has become a dangerous country of bandits and hunger. Across this landscape, a young woman must overcome terror and isolation to survive. Driven by determination and loyalty, she must leave the only home she has ever known, confronting both death and her past. Pushed to her uttermost limits, she will discover who she is and what she is willing to sacrifice.

The stand-alone sequel to the award-winning The World Without Crows, The World Without Flags is a story of survival, loyalty, and what we suffer for the ones we love.
