Sub-Zero

Rate this book
The only thing colder than the Antarctic air is the icy chill of death.

Off the frigid coast of McMurdo Station, in waters untouched by man, a deep-sea discovery is made—something ancient, intelligent, and deadly.

Aboard a classified DARPA research vessel, scientists are harvesting a never-before-seen species of Antarctic octopus. Its sub-zero venom could revolutionize a painkiller that numbs without side effects. But nature was never meant to be weaponized.

When a brutal storm slams into the vessel, all hell breaks loose. The onboard lab is destroyed. Containment is breached. And in the aftermath, one of the team’s top scientists begins to change. His mind unravels. His body no longer fully human.

Now, stranded in the most isolated place on Earth, the crew must survive something far more terrifying than the cold.

International bestselling author Matt James' high-octane, suspense-driven novel SUB-ZERO is back—refreshed, refined, and sporting a stunning new cover. Sure, the genre may be a little "off-brand" for Matt, but fans of his work will still feel right at home. His trademark elements are all rich world-building, compelling characters, and relentless action. Just be warned—the thrills come with some serious chills.

Aliens and octopi

This is the kind of book I love. Limited characters, insurmountable odds, plucky heroes. For the most part the story is good, with a different take on the "death in Antarctica" genre.
I liked the ship as a setting. I liked the characters both good and bad. Lots of action, scary scenes, blue blood.
Unfortunately there were quite a few grammatical errors - nothing earth shattering but definitely a distraction.
My biggest complaints are 1) repetition of irrelevant info. We know the captain is a good man who doesn't judge. You don't need to spend paragraphs telling us about it. And 2) stopping the action for an unnecessary note or reference or feeling. I found this irritating.
All in all I'm glad I read it.

Interesting story that needs better writing

This feels like one of the authors earlier novels, not his more recent stuff. The writing just isn't as good. There's a lot of random little things included in this novel that just don't need to be there. The racism backstories keep popping up in places, the daughter's drug addiction is mentioned once, but never again, and what could have been a great dark ending with Trip and his headaches is just never explained. The book falters during the third act when House and Donovan agree to meet hours later. Why not just meet right away? The final plan hinges on a lot of what ifs and wild contrivances. This definitely wasn't the author's finest work.

A fun sci-fi thriller

subzero is an entertaining and fun sci-fi thriller set on a DARPA research ship in the Antarctic. A meteor introduces an exobioloical creature to the waters, one capable of taking over people and controlling them. The writing is good, plot, characters, narrative quality, everything is there to form a solid read. Overall, 4/5 stars, highly recommended to fans of sci-fi thrillers!
