The Polaris Cycle

Rate this book
Survival is only the first step. The real war is just beginning.

Beneath the frozen waters of the Bering Sea, a long-buried secret is awakening… and it was never meant to see the light of day.

When the CSO team, led by Harvey Bennett, is sent to investigate a Cold War-era facility deep below the ocean’s surface, they uncover something far more dangerous than abandoned Soviet the Polaris Station, a hidden underwater base, isn’t just operational...

...It’s a ticking time bomb.

And its enigmatic leader, Admiral Strakov, has no intention of letting them leave alive.

As the station begins to collapse around them, Ben and his team must fight against ruthless mercenaries, a rogue faction with its own agenda, and the deadly force of the ocean itself. But the deeper they go, the more they realize Polaris is just the beginning. Someone bigger is pulling the strings. Someone who wants Ben to find them.

From the icy depths of the Arctic to the shadowy corridors of global power, The Polaris Cycle is a high-octane thriller packed with relentless action, shocking betrayals, and a mystery that threatens to rewrite history.

Down in the Dark Deep Sea

Why I love Nick Thacker's thrillers in one sentence: they start out gangbusters and go faster than light from there, the subject matter is so addicting and exciting, I can't put the book down, and the black-ops team CSO never gets a break.

Not much else left to say except that if you haven't met Harvey Bennett and the CSO team, you are in for a treat. I've followed Nick Thacker for a while and I've never been disappointed. I highly recommend his books.

A weapon that can control the tectonic plates is reactivated by the Faction

Polaris was an old Russian underwater base that was designed to be able to control the very surface of the Earth, able to cause earthquakes or tsunamis depending on where it is aimed, but it was too unstable to be used reliably. Now the Faction wants to resurrect it and the CSO team has been sent in to prevent this from happening. It soon becomes clear that the team was expected...
Another action-packed, suspense-filled romp with another discontinuity occurring early in the tale (are they deliberate or just a sign of a crap editor?). Moral quandaries, sacrifice, gun battles and face to face combat reign supreme in another enjoyable installment of Ben's story.

Under the Sea

Latest instalment of the Harvey Bennett series is a post cold war thriller. The usual roller-coaster of action, thrills and suspense (as well as the corny jokes), but with added introspection.

Nick never disappoints!

Just when your adrenaline level backs off and before you can breath a sigh of relief that the danger has passed…..the CSO group gets hit even harder. I know after reading this I need that beach vacation to relax!

Good read

The book kept my interest from the beginning. The characters were believable and true to character. It's just that I was not happy as to how it ended. Being left hanging is not my idea of an optimal read.
