Lifeafter; The era of the Revenants

(Art by me. Took me a while to do this. So this is the new book cover :3) Humanity has always been curious creations that never learnt quickly from their mistakes.. Greedy... and prideful... we'd do anything to achieve our goals... even if it meant ending the world... Scientists had experimented on humans for a long time, making different breakthroughs and some failures... but this one was their most astonishing and regretful discovery.. with a mistake in their calculations as well as their subject. A virus was created and this virus was passed on to Everyone in the hospital lab quickly causing the first zombie infected appearance. At first it was mild... but like a wild fire, it spread round the city and nearly around the world... humanity was pushed back, homes destroyed....bond broken.... and many more problems came. But after all, humans can adapt quickly. And quick did they adapt... creating weapons that work for both infected and mercenaries alike, humanity had found a way to survive again. Despite the population reducing to an absolute needle size... humanity didn't give up... And now.... something else seems to have appeared... something that would affect everything..
