The zombies that attacked Miami

A long time ago, there lived a family called the Stevens. They lived in Miami, and they had a dangerous job, which was zombie killing.
The Stevens had two children who were being trained to kill zombies if there was another outbreak.
One night while they were watching television there was a very loud bang which had come from their neighbors when they looked outside they could see that their neighbors had been in a big fight with a strange-looking creature that was covered in bits.
