Even the most talented of writers often gets stuck for ideas. Here's a story prompt for you.
"A chemical explosion destroyed a city, turning most residents into zombies. Total chaos. Story location is in a post-apocalyptic city named OKU City. Zombies walk the blood-filled streets during the night, while thugs roam the city during the sunlight. Nobody is safe. The only person who can save them is Kari, a woman with angelic powers."
I give you free reign! If you write something, please let me know!
