Extinction Horizon

Book 1, The Extinction Cycle

This book can be downloaded and read in Apple Books on your Mac or iOS device.


The worst of nature and the worst of science will bring the human race to the brink of extinction...
Master Sergeant Reed Beckham has led his Delta Force Team, codenamed Ghost, through every kind of hell imaginable and never lost a man. When a top secret Medical Corps research facility goes dark, Team Ghost is called in to face their deadliest enemy yet--a variant strain of Ebola that turns men into monsters.
After barely escaping with his life, Beckham returns to Fort Bragg in the midst of a new type of war. As cities fall, Team Ghost is ordered to keep CDC virologist Dr. Kate Lovato alive long enough to find a cure. What she uncovers will change everything.
Total extinction is just on the horizon, but will the cure be worse than the virus?
Self-publishing sensation and USA Today bestseller Nicholas Sansbury Smith comes to Orbit with the first book in his propulsive post-apocalyptic series about a soldier's mission to save the world.

Another great book by Nick Smith!

Another great book by Nick Smith, one of my top favorite authors.

This is a story about bad government (which I love), mutants (who doesn't love mutants) and the end of the world as we know it (always a winner). I enjoyed the characters and they seemed genuine to me. Of course there is the budding romance and i'm sure book two (hint) will further develop this. I would have liked a little more back story about the bad government scientist but maybe that's a prequel.

***** Possible spoiler for some *****

I liked the mutants - they were pretty scary. However I thought the physical changes occurred a little too swiftly. But then again, for this kind of genera you always have to suspend reality for it to work. I just think the changes could have spanned a day or two and maybe would have added more psychological horror to the infected as they consciously went through the changes. All in all, though, I definitely enjoyed the mutants.

I think the bad government guys could have had more exposure and suffered more. I think they got off too easy.

I'm definitely looking forward to book 2! Keep up the great work Nick!

Strap yourself in...

For all you adrenaline junkies out there (like myself) this book is a "keeper". Intensive research, realistic character development and non-stop action is signature of the author’s usual writing style. However, I think he’s ramped it up a few notches for this series. Lucky readers!

Delta Force “Team Ghost” is the best-of-the-best, accustomed to kicking butt and taking names. So what better way to test their mettle than pit them against a global pandemic of epic proportions? The result is 350 pages of brilliantly layered tension and suspense. If you don’t want to be up all night reading (like I was), start early.


Awesome book!!! :) This one will keep you on the edge of your seat, it has a lot of action and suspense. I loved it! Love the characters, Beckham is a great and loveable hero. Can't wait to read the next book in this series.
