Swarm - A Zombie Series (Book 1) by Alex South

The ultimate nightmare, the end of the world via zombie. To make matters worse, not that it gets much worse than being eaten by zombies, it all happens within a matter of days.

Paranoia is rampant among the survivors. Is there any way to know whether someone has been nibbled, bitten or infected?

Aside from full body inspections there is no way to be certain, which means the small groups of survivors have to trust their instincts when it comes to other survivors.

There needs to be more character and plot development if South intends to create more a fast paced and tastier morsel of literary flesh. The main character needs to stand out more from the others, especially because at the moment the healthy non-bitten characters are overshadowed by the flesh eating ones.

Perhaps filling in some of the blank holes would be a good idea. Where did it start, how did it start, who was the unfortunate patient zero? Is there a way to stop the zombie apocalypse?
Obviously or hopefully some of those questions will be answered in the next book in the series.
