This is an idea I was toying with. It's a novella about a couple who get into a car crash while arguing about the Husband's fidelity. The husband wakes up in the middle of the interstate to find that all the cars have disappeared and that his wife is dead. After panicking, he makes a short trip to the city and finds that it too is not only deserted and that plant life has turned it into a sort of literal concrete jungle. Someone is communicating to him with elaborate and noticeable graffiti and he gets calls over payphones from his wife, who is still alive but in an alternate version of the same reality that he's in. The vandal who communicates with the husband gives him instructions on how he could go about getting back to his own reality and how he can save his wife before these mirror realities crumble away.

Also, I finished a short story that I'll be editing and posting shortly once I find the time.
