Ithaka O. 
Because They Don’t Bleed Red [EPUB ebook] 
a short story

He’s just a delivery guy walking the surface of the earth…
…in an era when humans don’t rule there anymore.
Overcast skies. Greasy roads. Endless sonic tension.
That’s the cold reality a young man must face when he wants to get anywhere above-ground these days. It’s a risk. It can get deadly. Yet he must rise above the shield of safety to protect his loved ones.
If only the machine overlords wouldn’t notice.
