CENTRICITY:
​CENTRICITY CYCLE BOOK 1

A stolen child. The hunt for a world-altering tech. A scandal that could bring down an agency ... and a city along with it. 

Intelligence Officer Adasha Denali resolves disputes for Naion—using words, not weapons. But with her agency under fire and her mentor blamed for the failed op, she’ll have to get her hands dirty.

Racing to discover who’s undermining Naion’s security and why, Adasha runs headlong into corporate mercenaries, an engineered spy, and a man losing his mind to a new form of intelligence.

Meanwhile, the once-great immersion hacker Neon Nik is on the ugly side of broke, struggling to pay off circling loan sharks.

When he inherits a piece of advanced tech that throws him into Adasha’s path, threats of dismemberment become the least of his problems. Now he’s got a vortex of hired killers on his heels and a decision to make: sell out or risk everything to regain what he lost. And perhaps save his city in the process.
---
Enter Naion, a megacity at the heart of civilization’s rise from the ashes. In its towering arcologies, bodytech gurus upgrade the human chassis and synthetic intelligences whisper revelations through brainware. Here, powerful forces seek to determine whether humanity will forge a new path or repeat past mistakes.
Centricity takes the layered intrigue of Tom Clancy’s Jack Ryan, injects the future-noir of Altered Carbon and Blade Runner into its veins, and hands it a weapon fully loaded with the technopunk of Neuromancer.

-Edited by Michael Crowley, who worked on Andy Weir’s bestseller, The Martian.-

Centricity Reviews

Picture
"Set in the far future of the city-sphere of Naion, the world has evolved into complex arcologies after a number of catastrophic events. The story premise and concept give the plot more than enough depth for an imaginative story and character development. The world-building is as immersive as it can be in terms of technology enabling people to enjoy their entertainment, run their businesses and government, and find new ways to live and eat: who can resist vitamin-infused potato crisps? However, human flaws don't change and greed still rules."

"CENTRICITY is an immersive and atmospheric novel that blends sci-fi, espionage and thriller elements. Henderson’s world-building is particularly impressive, providing vivid descriptions of a society coping with unchecked exponential technological growth and rampant global environmental deterioration. His masterful wordcraft adds an authenticity to how life would feel in a future world where augmented reality technology is omnipotent."

"It easily earned a full five star rating from me and it is now on the list of my favorite reads of 2020 ... His impressive brand of world-building is entirely captivating and during my reading experience I felt like I could have stepped right into the world his characters inhabit."

"Gripping, intense, action-packed, Centricity will be as welcome to fans of SF and the cyberpunk genre as a top-shelf combat neural-link upgrade from your trusted local body shop. Delve into a web of high-tech intrigue, where the recyked air inside the city dome reeks of cheap carbon filters and sizzles with the static discharge of mag-accelerated high-velocity rounds..."
-Amazon.ca reviewer
"In Naion, almost everything seems to be hackable and virtual, and your daily life can be easily exposed. I’d be extremely paranoid if I were living in this dangerous, chaotic world. It’s a scary future to live in, with disasters at every corner."

DUPLICITY
THE CENTRICITY CYCLE: BOOK 2

Nik is on the run from forces he barely understands, but he knows what they want: the Acorn, a cutting-edge tech worth killing for. Without answers—i.e. leverage—he's a dead man. His search will take him to a faraway place just next door, where the graves are real but the bones are not.

Cyan Ivassa is the scion of an ambitious CEO, and to earn her place in the corporate empire she must revive a failing company. Also failing is the experimental brainware that's been keeping her alive since childhood. To keep her head, she'll have to confront her past and old bad memories more dangerous than any cut-throat competitor.

Facing corruption charges, Adasha is determined to prove her innocence and expose the real traitors before they silence her. With Maz and Rown busy chasing the Acorn, she'll have to look closer to home for help, putting her family in the crosshairs. But the risk is worth it, for if the agency falls, Naion falls, and the world falls with it.
"Nathaniel Henderson has fantastically realized cyberpunk island nation full of corporate intrigue as well as impoverished edgerunners."
-C.T. Phipps, author of Space Academy Dropouts and The Supervillainy Saga

“This is cyberpunk at its finest—fast, tense, and relentlessly imaginative. The immersive, neon-drenched world pulses with detail, and the cast of characters will stay with you long after the last page.” 
-D.L. Young, author of the bestselling Cyberpunk City series
