Repetition

In a day to day life in a world that slowly gets worse, a man named Charlie gains a rather strange gift. To relive the time from waking up that day to the point of his death, if his death happened that day. How will this power be used?

(A side, this is the first thing I've ever written beyond table top campaigns.. so keep in mind I don't have a sense of writing style....so don't be shocked if it kind of changes from chapter to chapter..once I get a concrete way of putting out my words I think I'll go back and rewrite everything so it doesn't feel like a dozen people at once contributed to the story.. and of course criticism is welcome... I kind of don't know what I'm doing and simply had an idea)
