Publisher Description

Artificial Intelligence is our last hope of saving the war-ravaged Earth in this near future science fiction thriller from the apocalyptic mind of New York Timesbestselling author Nicholas Sansbury Smith (Hell Divers, The Extinction Cycle, Orbs). The most advanced soldiers in human history are about to become obsolete. Engines. Genetically modified warriors that keep the great Nova Alliance war machine churning against the enemy Coalition. Most days, Engines are all that stand between salvation and chaos. Led by legendary Engine, Captain Akira Hayashi, Shadow Squad has fought on the frontlines for a decade. They are on the brink of victory when the Coalition launches a series of desperate and devastating attacks that cripple the Nova Alliance restoration sites vital to save the dying planet. As the sites burn and Earth’s hope of salvation fades, Shadow Squad is equipped with neural implants to connect them to Apeiron, the first hybridhuman-AI entity. She is coded for what Captain Hayashi believes is an impossible task—peace. But war isn’t the only threat to the Earth. Apeiron has uncovered a deadly secret with implications that could end all life. This rapidly approaching threat can be stopped only if humanity bands together on what will become known as E-Day, a pivotal moment that will determine the evolution—or the extinction—of the entire human race.

Love this military sci-fi thriller!

I absolutely love this new take on AI and what the future might look like. This is a great blend of military science fiction with a dash of science and techno-thriller. E-Day also has a ton of suspense with twists and turns. One of them caught me off guard. The characters are developed and all have interesting stories. I finished the hardcover in two days, and it’s a long book. When’s the next one come out? I’m definitely looking forward to more in this series!

Really interesting

A sprawling and epic story with super soldiers trying to save the world. Lots of twists and turns. Rc Bray does a great job. Highly recommended!

I have never been so impressed on the level of story and atmosphere that an author brings to life. I have been hooked to the extinction series and the characters that he has developed. I’ve read a lot of various authors and none have used the level of realism in military story telling and lingo that hits home to me personally. I recommend starting at all his earlier works and from the beginning because even though they have different universes. They all develop and grow in an evolution of stories that make you love the authors way of writing. I will be a follower until he puts down the pen.
