The apocalypse

Prologue

The year is 2029. Doctor Stevens is working on a new formula in her office with ten other doctors. She finally adds the last ingredient and mixes it up, making the formula she so desperately wanted to.
Doctor Stevens injected it into her husband, awaiting the results. She didn't know, however, that it was to make him a walker. He screamed in pain and started to transform into a terrifying walker. The doctor screamed in terror as the walker broke out of its chains and cuffs. Doctor Stevens ran out, abandoning her group and ran for shelter. What a mistake she made.
The walker turned the remaining doctors into more walkers, now 11 walkers. They broke out of the building and started to attack more people, many in complete shock of the event. By the end of the day, 20 walkers formed, many friends and family were devoured and became undead killers.
The year is now 2032, three years later. The city of New York is in ruins. Walkers devoured the city and almost everyone in it. Fortunately, a large group was safe in an underground haven where the walkers could not reach. There were about 30 remaining survivors hidden, dirty, cold, and hungry. But about 20 left to gather supplies. Jacqueline, or Jackie, is huddled in the corner, wincing as her leg was being bandaged from the pole that fell straight on her leg. Andy carefully wrapped her leg, him being gentle. "There. Better?" He smiled and Jackie smiled in pain. "Yeah. As better as i could get. Ugh. Where is everyone else? It's getting dark and late. Walkers would come out." Elizabeth came over and sighed. "They became walkers" the remaining ten survivors looked in shock. Jonah walked over, cuts and bruises all over his face. "That's terrible" lizzy nodded. "Yeah. And now, we're the only ten remaining survivors in the country." Murmurs were heard. The youngest member of the group, ivy, who was 12, stood up, clutching a knife. "Well? What are we sitting around for? We need to fight!" Andy shook his head. "Ivy, we can't. We are the only ten survivors in all of America. We need to stay safe" ivy sighed in annoyance but she sat down. Jackie sighed. "I just wish I could see my sister again." Andy placed a hand on her shoulder. "It's alright" he smiled. "I miss my brother" Jackie smiled softly but sighed. What will happen to everyone?
