"The author's sense of humor comes in the books. Many times I read a sentence and wondered how his mind came up with some of the ideas. I laughed often too. The nicknames!!! I find it very easy to suspend disbelief, even as a scientist. There is a little bit of everything in this book, political intrigue, calamity, eco-terrorism, WMDs, science, social issues, NJ mob families, military . . . and zombies, er . . . "the infected." It's almost like I can take every major movie/TV series growing up and put them all together, add zombies and creative writing skills and you get this series, making the series feel familiar and comforting, while still very fresh/new (which sounds impossible, but Neil Cohen did it)."
– Dr. Terry Oroszi, Assistant Professor, Molecular Geneticist, Terrorist Researcher, CBRN Defense Director, and Strategic Planner
"Neil Cohen's book is a must read. As a survivor of ten military deployments and hurrican Katrina, I must say that I couldn't put this book down. Those who love the end of the world type genre will love this book."
– Larry C. James, Colonel (retired) U.S. Army and Professor, School of Professional Psychology, Wright State University
"An interesting method of kicking off the zombie apocalypse that leads to an interesting twist in zombie anatomy."
"Details long missing from zombie lore are sure to please the zombie fan who wants answers."
"One of the best books I've read in a while in regards to the zombie apocalypse. This is a total different take from your usual zombie biting and infecting people."
– Anna Olvera, CREATORS.CO
"I can finally admit that Exit Zero has frightened me to the very core. Until now I've been a massive zombie fan and enjoyed the movies, books and TV shows for that they are; fiction.
This book is disturbing because it demonstrates the ease of how a massive pandemic could be engineered and controlled by any number of large corporations, terriorist cells, or even our own government."
"Neil Cohen is a tireless advocate, working to keep the zombie genre 'undead'."
– Robin Justice, WalkerStalkerCon
"There are countless examples of just how fluidly Cohen gives context to his outbreak, maintaining the same fantasy Zombie survivial scenarios we all love, but grounding it with some cynical home truths. There is no doubt that Cohen's fantasy world bears, all too worringly, halmarks of our modern society, and as organic as the parallels seem to be, I have never seen them used as astutely as they are in this franchise."
