Don't mean to seem like I'm only here to plug my own work, but I have a fanfic currently called "Lee's Second Chance" which is literally about him being given a second chance at life, starting on the day of the outbreak. But this time he has all the memories from his past life.

It's more supernatural than anything else. I try to keep the tenses right and the grammar proper. Currently, though, I am taking a break on it until after Christmas.
It only covers Episode 1 so far.
