Promise to Kill?

Sure flesh eaters were only real in stories, but when they become a reality, who knows how long they'll last? Emilia knows, she know's all too well when she loses not only her family but her best friends to the infection, now alone, she has to find a way to end this before it ends her.
Finding a small girl wasn't part of the plan though, much less raising her.
When she crosses paths with Leo again, there's something different..maybe it's the fact he's half flesh walker now? Soon after leaving OWL they come across a perfect little town, Boston, and not only is it haunted and flesh walker free, but it also holds secrets to the future, and the key to freeing the monster inside Leo, and with three simple words from one little girl: "Promise to Kill?" hell is let lose and death is ensued.
(Follow Emilia, as she raises Lilia, travels with Leo in search of their best friend Daffy and helps Leo fight off the infection that threatens to devour him. Will they find a cure in time to not only stop all the flesh walkers but also save Leo? Or will this prove to be too much for the fourteen year old crybaby?)
