Affliction Z is about a team of Navy Seals sent to Nigeria on a rescue mission. They enter an underground laboratory that was conducting research on biological warfare and attempt to locate survivors. However, they encounter hoards of people that are infected with the Z virus. The virus causes the afflicted to be extremely aggressive and impervious to pain.
This book is interesting and I like that the author provides a reasonable explanation for the beginning of the zombie apocalypse.
The story changes perspectives rather frequently, so you have to pay attention or you will end up lost and confused.
I give the book a B+
