A gripping mystery in a dystopian world

In The Agency- Operation Delta, we are following Agent 411, or Vanessa, a genetically modified agent. She accidentally gets caught up in a conspiracy within the Agency while investigating a security breech that’s linked the a murder of a potential rebel. We are also following Detective Miller who crosses paths with Vanessa when he is sent to investigate the homicide. While neither trusts the other, they agree to help each other and share information to unravel the conspiracy within the Agency. Additionally, we have the Rebels whose goal is the bring down the totalitarian government from within. I enjoyed this book. The dystopian setting is perfect for anyone who likes the genre. The characters were all well-written, with each being complex and dynamic in their own way. Vanessa dealt with so many internal struggles as she is loyal to the Agency, but is it true loyalty? This book is very fast paced and the author knows how to add just enough details to set a scene and not overwhelm the reader. There were a ton of twists, turns, reveals, betrayals, and conspiracies to make this a well-written spy thriller set in a dystopian future. I recommend giving it a read!

Great dystopian police thriller

I borrowed this book thanks to the Kindle Unlimited subscription that I share with my girlfriend, and I read it on my tablet using the Kindle app.

We follow Vanessa (Agent 411) and Detective Miller in their separate cases, which eventually merge together brilliantly. We are in a dystopian future where religion has been extinguished, and conspiracies are the trending topic. While investigating a breach linked to a strange murder, Vanessa discovers that the Agency she is working on, is not what it seems. More murders appear in front of her, while her life and the meaning of her existence are also in danger.

You will encounter all the elements of a typical police thriller mixed with political conspiracies. This type of story can easily become a mess with all the different links and clues discovered along the way, but the author does a great job of keeping it organized and creating a great and interesting setting. Vanessa and Miller are relatable—you always want to know more about them, and the author delivers just the right amount of information.

Book 1 ends with such a huge cliffhanger that it will leave you desperately wanting the author to release Book 2 now.

The Agency: Operation Delta (Part I) opens with a bang dropping you right into a dystopian world where knowledge can be deadly. The plots were twisting and dipping and sometimes hard to follow for me. That may just be because I'm not usually a mystery reader, but I found myself flipping back a few pages to make sure I remembered which character was being referanced as there were MANY and they're connections with each other was a sticky web of information.

I had trouble suspending belief that our main character, Vanessa, was so loyal to the Agency when she often addressed disparities in their rule. Honestly, it was hard to be invested since none of the main entities had true names. They were "The Agency", "The Rebels", and "The Enemy". I understand this was most likely a choice by the writer in order for the reader to create connection to the plot, but it was often jarring for me that even the players didn't have different names for these organizations.

Why don't the rebels call themselves freedom fighters since that's what they believe themselves to be? Why is there a civilian police force within this society which is ruled with absolute authority by the agency? And if forbidden symbols such as a cross pendant is cause for the death of the person in possession due to a "faith crime" why aren't any of the younger generation aware that such a thing is illegal?

I'm hopeful some of these issues will be fleshed out in the next book, but honestly, I'm still a bit confused long after I've read this book. In part, that's brilliant on the part of the author because I'm still trying to sort out my experience and filter it through what I know.

The book as a whole was an intriguing jaunt into dystopian storytelling. It's a 4-star read for me due to editing issues such as consistently dropping opening quotations in conversations. Overall, I'm hoping the holes in the plot are a clever nuanced way to let the reader feel the confusion of the people in this society and not a misstep on the part of the author.

It's certainly worth a read by anyone who enjoys mystery, twisting rides, and dystopian societies.

This is the story of a mysterious ‘Agency’ and its fight against an equally mysterious ‘enemy’, the nature of which entities is not elaborated, leaving it unclear as to who is good and who is bad. It begins with an intruder on Agency property who is caught while escaping by ace agent, Vanessa, but not before he’s hacked secrets that threaten to blow the cover on some covert project. About the same time, a student with computer skills is suspiciously murdered, with the two events being related. More murders follow, with victims missing body parts, and conspiracies are implied. As Vanessa attempts to resolve the mystery, she faces internal and external opposition, and significant danger, while a police detective who recognises clues to a linked past case becomes involved. What follows is a futuristic thriller with familiar tropes, such as genetically engineered people, as well as a lack of resolution, meaning there will be at least one more book in this series.

So, what’s it like? Well, it starts unpromisingly with a Prologue that isn’t. A Prologue is generally a foreshadowing, where something significant outside the direct narrative is revealed. However, the prologue here is really ‘chapter one’, with the named ‘chapter one’ involving the same protagonist in the same scene a little time later. I’m not trying to be pedantic here, but an author who knows their craft should appreciate this, and a misclassification at the outset immediately sets alarm bells ringing (heard of ‘first impressions’?). And the early writing is imprecise, too, for example, with ‘footsteps echoing’ on ‘sodden ground’ (er, no). Then into ‘chapter one’, and within a few paras there are clumsy word echoes and punctuation errors (missing open speech marks being a recurring theme), though perhaps the worst of the author’s peccadillos is the propensity to provide extensive commentary on dialogue, where we are told who said what, in what way, and why. This is a typical example:

“Do you have an address? I can head there now,” said Vanessa, determined to investigate.

In this case, Vanessa is one of two people in a conversation: it is obvious that it is she responding to the other person, so there’s no need to add the speech tag, while the latter explanation is completely redundant. Indeed, the author likes to narratively explains people’s thoughts rather than allowing action and dialogue to reveal them. This style slows everything down immensely and adds many superfluous words to the book.

So, to be clear, I got into grumpy mode quite quickly: this really does need another few drafts, and the author needs to sharpen her reporting of dialogue and internal thoughts. But what about the story per se? Well, it’s a bit odd in that the world is so unelaborated: it’s not exactly clear where this is taking place, who the different sides are, what society looks like, and so on, with dribs and drabs of information filtered in as-and-when needed (for example, we learn early on that Vanessa isn’t sleeping, and only learn that she is stressed over her last mission going wrong when someone mentions it to her off-handedly several chapters in). Still, the story does actually rattle along at a decent pace, and there are moments of drama, intrigue and interest. Although it took me awhile, I did at last get into it, and certainly enjoyed it at times and wondered what might happen next. The plot is intricate and quite well handled, and the world-building, though slow, is actually rather cleverly done in revealing a somewhat dystopic state. So, it’s certainly not terrible! If only…

The Agency - Operation Delta is a dystopian thriller that revolves around the two central characters of Vanessa, or Agent 411, a genetically enhanced human that was conscripted as a child into an organization called The Agency, and Detective Miller, a member of the police force whose experiences with The Agency have left him cynical and wary of cooperating, over the years. But when a security breach takes place at the Agency, leading them to cross paths, Vanessa and Detective Miller reluctantly join forces in order to unravel a series of gruesome, mysterious murders that are taking place in relation to the data breach.

While the plot itself is interesting in its conception, I feel as though it could have been fleshed out a bit more. Certainly, I would have appreciated more detailed background information about the world and some of the events that are referenced prior to the start of the story. I felt a little frustrated when a concept, such as Vanessa's genetic enhancement, is introduced, but we're never given any details about what exactly it entails, aside from some vague snippets here and there. It's as if she is trying to keep this important plot detail as a much a secret from the reader as she is her enemies!

In terms of The Agency itself, it comes across as this shadowy, sort of amorphous organization that does spy-like things, but again...we aren't given a lot of details about it or how it's actually organized. And frankly, the fact that it's only ever referred to as "The Agency" is a little unbelievable and more than a little generic. Giving it an actual name would have fleshed it out a little more and made it seem more real to the reader. As it is, it's very frustrating as a reader to see Vanessa so dedicated to a place that conscripted her as a child and gives her no reasonable motivation for such loyalty. We never learn enough about the place to understand why she isn't reluctant to work for it, or resentful of it, like Detective Miller's experiences with it.

Finally, there is a minor plot thread about religion that's brought up now and then, but is mostly forgotten about. I would have liked to get more information about it and see it intersect with the main plot a bit more. About all it really seems to establish in this book is that religion has been outlawed and supposedly eradicated, and oh yeah, it's evil and bad, etc, etc. While I find that rather off-putting as a religious person myself, I thought maybe it played some wider role in the plot and that Vanessa might start to question her preconceived notions about it a little more, but that never really happens. Again, just as with "The Agency," why isn't she questioning anything? Why is she so trusting of what the government and her dystopian society think about religion, and why is she so loyal to an organization that has never done anything that we know of to earn that loyalty? It's quite maddening, as a reader, to see how little Vanessa stops to think through the larger implications of anything.

But is that the point? Is Vanessa brainwashed and she doesn't realize it yet? Does religion play a larger role in the plot as the series goes on? Are they being lied to about it, as well as everything else? None of this is ever addressed, and even the main plot itself is never really resolved. You're left with too many questions and unresolved plot points, and it makes one reluctant to read any further installments in the series.

The Agency: Operation Delta is a thriller set in the near-future where an authoritarian government has taken over through "The Agency", which dominates the country. In response to a religious war, the borders are closed and freedoms are stifled, and The Agency fights against both "the rebels" (internal agitators) and the "the enemy" (people in other countries).

In this dystopian world, we follow Vanessa, an agent of the Agency. She has a special past, being involved in something called Project Ruptura. She is quick to break the rules of her Agency when it suits her, but in a very "do as I say not as I do" way, frequently tells a teenager named Laura Reid that she should follow the rules. Laura's whole town is being relocated for "safety" against their will following the execution of her boyfriend for the crime of unknowingly holding a religious icon (a cross). Vanessa spends time with Laura but mostly seems to find her annoying, and spends a good amount of time being patronizing to this girl, telling her about her freedoms while she is branded traitor-adjacent and is being held in a fenced-off area surrounded by armed guards.

In the second PoV, Detective Gary Miller gets wrapped up in the main plot, which is that there's been a murder where the victim's lungs were removed. This organ removal continues as the novel progresses, and it's an effective way to build up the murderer as a real gruesome person. Miller's police force is at odds with the Agency, which suggests the Agency's control is not nearly as complete as we're initially led to believe. Miller is trapped between his pursuit of the truth and the very real consequences of dissent in this repressed society.

There's a certain vagueness to everything that can make it hard to follow at times: the rebels and the enemy were difficult for me to tell about for a good portion of the novel, for example. Vanessa gets sidelined to the town relocation early on, and those scenes seem to exist to give Vanessa a foil for her loyalty to the Agency, but ultimately don't factor into the conclusion of the main plot. It's still not quite clear how this society works, having cut itself off from the rest of the world, or how it even managed such a feat. And there are many moments where the book overexplains how people are talking and what they mean when they say something that became quite distracting.

Still, when the book gets to the action sequences they'll well done, paced well with good blocking so I understood the action. The villain is a good one, dangerous and lurking behind the scenes until the reveal and appearance in the final third. There are betrayals and Vanessa (and the reader) can never truly be sure where every character's loyalty lies.

The ending (not spoiling here) only resolves the main murder plot. Many threads are still open and the very last scene is a set up for novel two. It will be interesting to see how the series develops.

"The Agency: Operation Delta" by Anastasia Thomas plunges readers into a gripping narrative where the lines between power and morality blur amidst a backdrop of imminent war and biological threats.

Vanessa, a genetically enhanced agent for the Agency, grapples with the fallout of a failed mission and a deadly virus contracted during a terrorist attack. As she goes deeper into a web of espionage and treachery, she must confront her past and make decisions that could change her life and their fractured society. Detective Miller, tasked with solving a string of murders linked to the Agency, pursues a relentless quest for truth and justice, driven by personal vendettas and a scepticism of the Agency’s motives. As their paths intertwine, both must face a maze of secrets and ethical quandaries, questioning their loyalties and confronting the murky waters of right and wrong.

The content of "The Agency: Operation Delta" is masterfully crafted and offers a palpable mix of suspense and psychological depth. Thomas’s writing style is both compelling and evocative, and draws readers into a world fraught with danger and intrigue. The book’s appeal to its target audience—fans of thrillers and complex moral dilemmas—is undeniable, as it offers a unique blend of action and introspection. The meticulous editing ensures a smooth reading experience, while the “it” factor lies in the novel’s ability to keep readers on the edge of their seats. My favorite part of the book is Vanessa's internal struggle and the moments of vulnerability she shows, which add layers to her character and make her journey profoundly relatable.

While "The Agency: Operation Delta" excels on many fronts, one might suggest that certain secondary characters could benefit from further development to enhance the emotional impact of their arcs. However, this is a minor quibble in an otherwise stellar narrative.

Readers who shy away from intense psychological thrillers or morally ambiguous narratives might not appreciate this book. However, it is a perfect fit for fans of authors like John le Carré and Robert Ludlum, who will find themselves engrossed in the tome's intricate plot and dynamic characters.

Anastasia Thomas’s "The Agency: Operation Delta" makes a significant contribution to the thriller genre, and offers a potent mix of suspense, ethical reflection, and rich character development. Its potential to become a beloved classic is evident - a must-read for enthusiasts of high-stakes espionage and psychological drama.

A Thrilling Dive into Espionage and Dystopia

If you're looking for a fast-paced, twist-laden thriller with just the right amount of dystopian grit, The Agency: Operation Delta by Anastasia Thomas is an absolute must-read. From the first page, it hurls you headfirst into a world where secrets and lies are currency, and every character is a ticking time bomb. At the heart of it all is Vanessa, a genetically enhanced agent grappling with guilt and the crushing expectations tied to her abilities, and Detective Miller, whose personal vendettas and distrust of the Agency add layers of tension to the narrative.

One of the things I loved most was the intricate dance between Vanessa and Miller. Their evolving trust—fragile, tense, and deeply human—adds a powerful emotional undercurrent to the story. Both characters feel complex and real, weighed down by their pasts but determined to fight their way forward. Vanessa, with her inner struggles and haunted past, is as relatable as she is dangerous, and Miller’s clashes with the government over his family issues make him a wild card you can't help but root for.

The world-building is a masterclass in subtlety. The dystopian backdrop unfolds gradually, like puzzle pieces slotting into place. Instead of overwhelming with exposition, Thomas trusts you to keep up, which makes the setting feel lived-in and authentic. I found myself drawn deeper and deeper into this shadowy world with every page. The themes—moral ambiguity, power struggles, and ethical dilemmas—give the story depth without bogging down the action.

And speaking of action: this book moves like a bullet train. There’s a constant sense of motion, and the twists hit hard. Just when I thought I had things figured out, Thomas threw in another curveball. It’s a rollercoaster ride, where betrayals lurk around every corner and every choice carries a heavy cost.

If there’s one thing that left me hanging, it’s the ending—but in the best way possible. Not everything wraps up neatly, and I can already feel the anticipation building for the next installment. It’s the kind of ending that lingers, making you wonder about what’s to come and keeping the story alive in your mind long after you’ve turned the last page.

The Agency: Operation Delta delivers on every front: a gripping plot, complex characters, high-stakes suspense, and a dystopian world you can practically taste. It's the perfect blend of action, intrigue, and emotional depth. I can’t wait to see where Anastasia Thomas takes this story next—because after this, I’m all in.

In the electrifying introduction to Anastasia Thomas's series, "The Agency - Operation Delta" takes readers on a suspenseful ride teeming with intrigue and hidden agendas. The novel effortlessly immerses us in a shadowy world where intelligence works and deceit reign supreme. The story primarily revolves around a secretive agency embroiled in an enigmatic mission, but what makes it particularly engaging are the layered personas and the intricate relationships that define them. The narrative is a labyrinth of mystery where every corner turned could mean ally or enemy, capturing the reader's fascination right from the start.

Thomas utilizes her mastery of storytelling to construct a riveting ambiance, blending realism with tension. The author demonstrates a keen understanding of human psychology, crafting characters with deep emotional complexity. You become invested in their internal struggles and ever-changing loyalties, as much as in their high-stakes external conflicts. This humane touch acts as the book’s pulse, keeping the audience enthralled with both the palpable suspense and the profound emotional undercurrents.

As the storyline progresses, "The Agency - Operation Delta" remains relentless, maintaining a breakneck pace that ensures readers are effortlessly drawn deeper into its world. The narrative threads are skillfully woven, leaving just enough hints without ever compromising the element of surprise. This meticulous approach encourages readers to engage with the story actively, piecing together the plot in a manner that is as gratifying as it is absorbing.

What truly elevates this spy tale to new heights is the atmospheric setting, and vivid descriptions that pull you directly into the agency's secretive operations. With each scene, Thomas paints an evocative picture rife with tension and anticipation. The settings, ranging from bustling urban landscapes to covert hideouts, are crafted with such precision that it's hard not to become an active participant in the unfolding drama.

Given its spellbinding narrative, complex character development, and immersive settings, "The Agency - Operation Delta" earns a perfect 5-star rating. It is a literary symphony of espionage, personal dilemmas, and cunning maneuvers that will leave readers gasping for the next installment. The novel is a testament to Anastasia Thomas's talent in constructing an enthralling world that promises to captivate audiences long beyond its closing chapter.

I just finished reading The Agency: Operation Delta and it was a thrilling ride from start to finish. The story plunges you into a world on the brink of chaos, where religious and biological warfare threaten to upend society as we know it.

The protagonist, Vanessa, is a genetically enhanced agent working for the mysterious Agency. She's haunted by a past mission that went sideways and is grappling with exposure to a deadly virus after a terrorist attack. What I found most compelling about her character is how she's constantly torn between her duty and her conscience. Even when she's reassigned to a seemingly mundane task of babysitting evacuated kids, she can't shake the feeling that something bigger is at play—and she's determined to uncover the truth.

Then there's Detective Miller, a seasoned investigator assigned to a series of gruesome murders linked to the Agency. His skepticism and personal quest for justice add another layer of depth to the story. I particularly enjoyed the dynamics within his family—his wife's job and his daughter's rebellious attitude create this underlying tension that mirrors the societal conflicts happening around them.

Anastasia Thomas does an excellent job of weaving together these two narratives. The pacing is spot-on, and the plot is filled with twists and turns that kept me guessing. What I appreciated most is that the world-building is done organically. Instead of dumping a ton of background information on you, the dystopian elements are revealed through the characters' experiences and interactions. It feels natural and keeps the story moving.

That said, the book does end with several unresolved threads. While this definitely has me eager for the next installment, I was left wanting a bit more closure on some of the plot points. It feels like the story is just getting started, and I'm looking forward to seeing how it all unfolds.

If you're a fan of dystopian fiction or techno-thrillers, I'd highly recommend giving it a try. Anastasia Thomas has crafted a story that's both entertaining and reflective, with characters that stay with you long after you've turned the last page. I'm definitely keeping an eye out for the next book in the series.

Intricate world-building and great characters!

The Agency - Operation Delta (Part 1) by Anastasia Thomas is a near-future, dystopian book that starts with a bang and goes straight into an action sequence. Vanessa, a genetically enhanced agent, interrupts a crime in progress, with the criminal inexplicably preferring to commit suicide rather than get caught. From there, the story evolves into a dark, complex, fast-paced, cat-and-mouse game as Vanessa (who was conscripted into a secretive, shadowy organization called "The Agency") defies orders and conventions to get into the heart of several brutal murders, despite getting into trouble for her curiosity and tenacity. She does this all with the reluctant help of (and sometimes despite the interference of) a hard-boiled detective named Miller. Miller, who has his own problems within his family, is very wary of Vanessa and the Agency in general, so there's a lot of friction between them that acts to keep the story going.

The writing is good, the dialogue is sharp, and there's enough going on at all times to keep a reader's interest (not necessarily all action, though, as there's also a lot of talking and investigating going on). The mystery reaches back into the past and deep into the heart of the organization itself, culminating in an explosive ending that is also a cliffhanger, as the book is the first of a series. There are a lot of twists for people who like that sort of thing and a lot of complex character-building so that no one is entirely good or entirely bad. In fact, it's sometimes hard to figure out who is a hero and who is a villain, which is always interesting. I liked that Vanessa--although certainly badass, was also vulnerable so that you didn't feel like she was a superhero despite her enhancements.

All in all, this is an intriguing political thriller with a dash of science fiction that is an excellent addition to the genre.

Compelling Thriller


I borrowed The Agency: Operation Delta (Part I) by Anastasia Thomas from the Kindle Unlimited Library and read it using my Kindle Unlimited subscription.

I found this book to be a solid, fast-paced thriller set in a dystopian world. I liked how will it is structured: From the very start, I was intrigued by Vanessa, a genetically enhanced agent with a troubled past. I liked how her internal struggles, especially dealing with a failed mission, gave her a lot of depth. I also enjoyed the twist: As the plot unfolded, I found myself really invested in her character, particularly as she faced moral dilemmas and complex choices – this si the norm of heroes!!

I enjoyed the storyline; especially involving Detective Miller – this added another interesting layer. I appreciated the dynamic between his skeptical approach to the Agency and Vanessa’s loyalty to it. I also liked how their paths eventually intertwined, which brought more tension to the narrative. The mystery surrounding the murders and the traitor within the Agency kept me hooked, and I thought the espionage elements were well executed.

However, I did feel that some aspects of the world-building were a bit vague. I wanted more context on the larger society and the forces at play. This would have made the stakes feel even higher. The pacing was mostly good, though there were moments where I felt the dialogue was over-explained, which slowed things down.

Overall, I enjoyed this book and found it compelling. I’m definitely curious to see where the story goes in the next installment.

Operation Delta follows Vanessa and Detective Miller in a dystopian world policed by The Agency. I liked the characters of Vanessa and Miller; they are both multilayered and complex, and the story weaves around their flaws and strengths to create quite an intriguing tale of misdirection. Although it’s dystopian, there’s no world building info-dump at the start, it’s close enough to our world that what has transpired to lead them to dystopia weaves into the narrative seamlessly. The world itself creates the plot, with Vanessa originally tracking a hacker, but gets surprisingly taken off the case to babysit evacuated kids. Does she stop investigating? Of course not. So rounded is Vanessa, her past continually affects her actions. Conscripted as a child, she is “genetically enhanced” although it’s not clear what that enhancement gives her. The people she grew up with weave throughout her investigation. With Gary Miller also involved, from the police side of things, the two intersect and learn to trust one another. Miller himself is a jaundiced cop, with a by-the-book partner and an intense distrust of the Agency thanks to an unsolved case many years before the story.

This is the first in a series, though the plot resolves nicely, there is a hanging thread that needs resolving. I’ll definitely be on the look-out for future books in the series. Anastasia Thomas’s writing is clear, crisp and paced well, so future books should be excellent.

A Gripping Blend of Espionage and Dystopia

"The Agency: Operation Delta (Part 1)" by Anastasia Thomas is a compelling addition to the thriller genre that seamlessly intertwines espionage with complex moral dilemmas. The narrative follows Vanessa, a genetically enhanced agent, as she navigates the treacherous waters of a shadowy organization known as the Agency. Her internal struggles—fueled by a failed mission and the burden of her enhancements—make her a relatable and multifaceted protagonist. Detective Miller complements her journey, with his own personal vendettas and skepticism towards the Agency adding depth to the story.
What I particularly appreciated about this book is the intricate world-building. Rather than overwhelming readers with exposition, Thomas reveals the dystopian setting organically through character experiences and interactions, creating a lived-in atmosphere that feels authentic. The dynamic between Vanessa and Miller is another highlight, as their fragile trust evolves amidst the chaos, adding an emotional undercurrent to the plot.
Though some secondary characters could use further development, the overall narrative keeps you guessing with its twists and turns. The unresolved ending leaves readers eager for the next installment, promising more intrigue and suspense. Fans of dystopian fiction and techno-thrillers will find much to love in this gripping tale.

“The Agency - Operation Delta (Part 1)” by Anastasia Thomas, is a taut, futuristic political thriller, and is not a complete story arc. Vanessa is an Agent for “The Agency,” a CIA-type organization who has been genetically enhanced. She believes an implant the Agency put inside her is necessary to keep her alive; thus, she does not think she could ever leave the Agency. When a security breach occurs at the Agency, Vanessa, who is haunted by a past failed mission, captures an intruder, but the man takes a poison pill before he can be interrogated. From there, her actions seem destined to cause her trouble. She continues to investigate the case of a murdered hacker who had obtained access to the Agency’s computer system even after she is ordered off the case and relegated to a security detail. Nevertheless, she meets Det. Miller, who is a detective investigating the hacker’s death. He later contacts Vanessa when he comes upon evidence that seems to connect the hacker’s death with an unsolved cold case: the double murder of The Agency leader and his wife and kidnapping of their daughter. Vanessa’s contact with Det. Miller could be dangerous for them both. This twisty plot held my attention through to the explosive finish.

Sci-fi Jason Bourne Type Story

The Agency- Operation Delta Book 1 is an espionage investigative sci-fi thriller that reminded me of a female version of Jason Bourne meets NCIS. You have genetic enhancements and dystopian marshal law adding to the tension of the story. The shadowy group that the book is named after struck the right chord of morally gray and terrifying. There is a level of investigative mystery that helps to balance out the action. The book is well written with some gems such as “The struggling air conditioning system waged a losing battle inside the hall against the thick, musky scent of adolescent sweat”. There were moments of great imagery throughout and I saved a lot of quotes on my kindle. That being said, I wish there had been a little more put in about the lore and the world-building. The action kept the book moving but that was what kept it from being a five-star read for me. The closing line of the book made me excited for the story to continue and made me mad that this book had ended: “They were not just survivors but soldiers on the frontline, and the fight for their lives had just begun.”

We follow the very skilled Agent 411, AKA Vanessa, through a very revealing operation. Her quest to uncover the significance of an invader in an Agency station leads her to learn much more about the enemy, the rebels, people of faith, herself, and the Agency itself. Along the way, she questions everything and everyone: herself, her coworkers, her bosses, the rebels, and yes, even the Agency.

An entire community was evacuated because of a faith crime when one teenager gave a relic (a Christian cross) to another teenager. Both faith and articles of faith are illegal, and Agent 411 was sent to separate the teenagers of the town from their families and put them in a sports complex surrounded by shock wire “for their protection from the enemy.”

I’m anxious to see if Vanessa realizes society’s belief in the protective nature of the government and her own acceptance of a benevolent Agency is actually a self-preserving religion more deadly than the one she is persecuting.

Religion:(n) a cause, principle, or system of belief held to with ardor and faith (Mariam Webster Dictionary)

The Agency – Operation Delta is the first book in the series by Anastasia Thomas. It is an espionage thriller set in a dystopian futuristic world. Vanessa (Agent 411) is one of their most-skilled agents at “The Agency”, a CIA type of government institute. It starts off with an exciting chase scene with Vanessa showing off some of her cleverness and abilities. But she has a secret that she does not want exposed: as a child she was the last remaining patient of Project Ruptura: a scientific experiment that got both of her parents murdered and she, kidnapped. When there is an information breach of “Project Ruptura” related to a murder investigation, Vanessa teams up with Detective Miller to discover the truth amid all the deceit, cover-ups and gruesome murders involving missing organs. Believable world building and character development make this a great scifi/spy story. Vanessa is a great, tough, straight-talking female main character that I always enjoy reading about. I found the pacing gets a little bogged down at times with all the information and characters involved. But well-written and executed thriller with a beautiful front cover design.

This is a gripping dystopian thriller. To that effect, it blends political intrigue, espionage, and moral dilemmas. It takes place in a world where truth is dangerous. Does this ring a bell with your current work environment?

The opening chapters immediately set a cinematic tone and you can feel the tension with secret meetings, government surveillance, and a fearless journalist flirting with corruption at his risk.

Then enters Vanessa, an operative haunted by failed missions in a world of spies and betrayals.

Compared to other dystopian thrillers, this book delivers fresh urgency but it also leans on familiar tropes such as "shadow agencies", government conspiracies, and resistance.

I enjoyed the depth of its protagonists. Sarah’s battle for truth and Vanessa’s struggle within the system offer contrasting perspectives.

The writing style is immersive and - I would say - atmospheric. The pacing makes every scene feel like part of a blockbuster movie. It might be tiring and overkill for some readers.

It doesn’t completely redefine the genre, but it will keep you hooked if you're a fan of political thrillers.

The Agency: Operation Delta by Anastasia Thomas is a rather unusual, clearly dystopian book. As a thriller, it features a mostly fast pace, with but a few more long-winded portions, which add to the complexity of the novel. I think one strength of the book is its exploration of morality and harsh dilemmas the characters are confronted with.
The plot revolves around Vanessa an agent with a more uncommon disposition (no spoilers - but think of a brave new world), and Detective Miller. They make their way through an entanglement of espionage, treachery, and warfare. The purpose in their mission the two find (or seek to find) within themselves adds to the moral polarisation.
The author shows an outstanding talent in world-building (not always to the general comprehension, but leaving room for guessing and imagination), character description, and careful persecution of a storyline, rife suspense.
Now it is important to note that the book is the first part of a series. The end is accordingly largely open. Overall, brilliant book, and highly recommended!

The book got off to a good start, introducing perspective characters Vanessa and Miller. The Vanessa scene is high action, but I felt like I got a good idea who she was. The Miller scene give a good idea of the politics going on in the World. The story moves along with both perspective characters suspicious of something they are not supposed to know about or involve themselves in. The author does a good job establishing a sense of tension and mystery here. The author brings the past into the MCs’ current lives. It's done in a slow developing manner. That works well in this book because the plot and people are very intricate. I also liked that Miller’s wife’s job and his daughter’s attitude are a bit in conflict with the current government which is at war with a group of rebels. This adds to the ever-growing sense of danger. Overall, I think this book will appeal to readers of dystopian science fiction, but it will likely appeal even more to lovers of techno thrillers. I recommend this book to fans of both those genres.

This is a book that delves into a world of secrets and gray moral lines. Vanessa is a genetically enhanced agent, torn by her loyalty to the Agency and the submerged truth inside herself. Her alliance with Detective Miller pushes them both further into a web of conspiracies, betrayal, and personal struggles.

The story’s strength lies in its intricate balance of fast paced action and reflective moments. Vanessa’s haunted past and the ethical dilemmas she faces lend her a deeply relatable edge, while Miller’s gritty determination brings another layer of tension. Their evolving trust feels real and earned, a highlight in the narrative.

The world-building is subtle and immersive, pulling readers in without overwhelming them with detail. Themes of power, ethics, and survival add depth, while the relentless pacing keeps you hooked. Though the ending leaves some threads untied, it does so in a way that builds anticipation for what’s next.

This gripping blend of action, suspense, and moral depth is an engaging start to the series.

This book was a super fun ride. The world building was impeccable and poignant. The characters were vivid and real. They were well rounded and just exciting to read about. I really loved the gritty old detective in the book too, what a nice touch. I was rooting for them. Even the side characters had their own depth. The dialogue was great and real. I thought the description was great and the writer is very talented.

The story itself was a fun spy thriller. It reminded me of the old Alias tv show a bit with Jennifer Garner, though Vanessa was way more hard nosed cynical. But still, it was just fun with all the different agendas every faction had. The world itself is a fictional contemporary country in a dystopian governmental climate, which was a very nice sandbox so everything seemed familiar enough but was excellent escapism. Some typos but happy to look past that because I loved the story.

The story ends on a cliffhanger but felt complete enough and I’m excited for a book 2!!!

The Agency - Operation Delta (Part I) by Anastasia Thomas is a fast paced thriller set in a dystopian future. Things are bleak: "We live in a world of closed borders, of absolute control. Religion has been banned, and books and symbols destroyed. There is no freedom here." The plot is interesting, with a few twists and turns. The main character, Vanessa is well developed. The dialogue throughout the story is skillfully done, progressing the story without feeling too unnatural. The author includes clever moments like this to keep the story relatable: "Why don't you just take your evidence and go?" Miller retorted. He grabbed a bunch of tissues and began dabbing at the coffee stain on his pants." Anastasia is a skilled writer whose style keeps the reader engaged. The story is fast paced, well worth a read! I will close with my favorite quote: "It's best not to chase ghosts, Ms. Miller. The past is dangerous ground."

An excellent dystopian thriller, that had me flicking to the end: we follow Vanessa, a conscripted agent in a totalitarian society, as she investigates a series of mysterious murders that point to a deeper conspiracy within her agency.
The author excels at world-building, creating a claustrophobic atmosphere where freedom is a distant memory and every action is monitored. The political intrigue feels authentic, while personal relationships add emotional depth to the narrative.
The pacing is well set, with each chapter building tension. Character development, particularly of Vanessa and Miller, is nuanced and believable. Their moral dilemmas and internal struggles resonated with me.
The novel successfully combines elements of thriller, dystopian fiction, and political drama, culminating in a thrilling train attack that left me eager for the next instalment.
A compelling story that tackles themes of loyalty, freedom, power. Good stuff!

From the beginning, you're thrust into a world that's tangled in deceit, uncertainty and a danger. The author does a good job of maintaining suspense throughout the novel, and I loved her choice of certain words to describe scenes. It definitely added to the imagination and made for some lovely story telling.

At times, I found that the plot developed quite quickly, and I had to go back to read a few sentences to keep up with the story that unravelled. There were a number of characters added to the story, serving as effective sub-plots to support the main one.

Sometimes I felt sorry for Vanessa to be in such a work environment; other times I felt that she was weak to handle the calamity that came her way. Regardless of how I felt about her at various parts in the story, the plot always kept the story moving forward and leaving you with a yearning to know more.

At the end, the book ends in a manner that sets the foundation for the second book.

An interesting book

It is an incredible book, a lot of intrigue, corruption, plots, plots within plots. Betrayals behind the corners, traitors who turn out to be allies and allies who really are not. I have immensely enjoyed reading this book, the plot is good and well written with unexpected twists. There are many characters involved, each with their role. My only drawback is the ending. It is not that it is an open ending, it seems that they had split the book in half and none of the plots were resolved, it forces you to read the next volume but instead of leaving you with intrigue, it leaves you with almost all unanswered questions or without being able to understand the relationship between certain events. I would have preferred a conclusion to part of the plot, too many open fronts.

Coming in hot from an Australian author, Anastasia Thomas hits readers in the face with a gripping story that is one that we don’t want to endure in real life. This novel is fast paced, with a very dystopian overlay and feel to it. This is done excellently throughout the book, starting off quite subtly at first.
The story evolves as it follows Vanessa into the deepening dark world. Her work at the Agency throws her into the forefront of this dangerous world. Without wasting too much time, the book moves at an awesome, fun, exciting pace, throwing twists and turns at you.
The second part of this story sure promises to be even better than this first fiery installment. I think most readers will be pleasantly surprised by the cliffhanger, and I personally can’t wait for book 2. If you are a fan of thrillers, conspiracy and or dystopian works, I would highly recommend The Agency!

I enjoyed this book, I found it gripping and was hooked all the way through, always eager to know what happened next. I found it engrossing to see the mystery slowly build up to the ending, which was satisfying, and left me excited for the story to continue in the next book.
I had empathy for characters
I thought that the world building was very good and the dystopian setting worked very well for the story. I particularly appreciated the deliberated vagueness around who is the “enemy”, I felt this added to the menacing undertone of the whole story.
I did find that the timelines could be confusing. There were occasional plot jumps where I felt like I had missed something. Perhaps these were deliberate to add to the sense of confusion and the difficulty untangling the truth.
All in all I would recommend this book, it was an enjoyable and easy read

This was an enjoyable fast-paced read with lots of twists and turns in a dystopian society filled with dark secrets and questionable morals.

The characters were so well developed, and I thought the growing connection between Vanessa and Detective Miller felt authentic, and quite powerful. Vanessa's guilt over her genetically enhanced abilities and connection to the Agency adds an interesting and fragile insight into her character, and Detective Miller's mistrust of the Agency moves the plot along at an exciting pace.

With its sophisticated dystopian world-building and gripping action, The Agency: Operation Delta is a great debut which left me excited to see what happens in the next instalment.
