A computer-hacking teen. The girl who wants to save him. And a rogue mirror reflection that might be the death of them both.

In private, seventeen-year-old Brandon hacks bank accounts just for the thrill of it. In public, he looks like any other tattooed bad boy with a fast car and devil-may-care attitude. He should know: he’s worked hard to maintain that façade. With inatt

I'll have to be honest here and say that this is a book you'll need to suspend a great amount of disbelief to take seriously. Not that I don't find cyberthrillers beyond the realm of feasibility! Of course they are and I find them extraordinarily fascinating in fact. One of the new battlegrounds we have today is the virtual space, as we find ourselves depending on technology at an exponential rate - from information to vital data to bank accounts and many more. Identity thefts happen, bank accou ...more

I was lucky enough to get to read this book before publication, and I READ IT IN ONE NIGHT. Seriously, it is a majorly nail-biting page-turner. I could not put it down, no matter how sleepy I was!

I honestly haven't seen anything else quite like this out there. It's an original, beautifully-written, trope-busting cyberthriller, with totally non-stereotypical characters you will really root for, twists you will never see coming, and an unusual and clever hacker protagonist who often veers into ant

Duplicity is a book I can easily classify as brain candy. I had a lot of issues with the book itself but the premise just made it so much fun to read about even if the main character and  I didn’t get along at all.

This book is fantastically imagined and the fact that I am not a computer programmer and barely understand HTML, did not hinder my understanding. The author never left us technologically challenged people out of the loop (at least

This was a weird YA sci-fi with a definite cyberpunk vibe to it. The setting was contemporary but some sci-fi twists added the cyberpunk vibe. The story was a fast paced psychological sci-fi thriller that threw in a tad of romance.

Brandon is a 17 year old genius hacker with a self-destructive streak who suddenly finds his life turned upside down when someone hacks his computer and warns him to mend his ways. It only gets weirder from there as Brandon's own reflection begins to take on a life of

Alright, computer nerds, this one is for you. Apparently there's this whole genre of "cyberthriller" books out there, but it's the first I've heard of the term (I know, I'm woefully ignorant). The only book I've read that even remotely resembles Duplicity is Ready Player One, but that is a dystopian-action/adventure-computer game mash up, whereas N.K. Traver's book is more mystery-thriller-science fiction. It's about a computer hacker, Brandon, who wakes up to find that his reflection is moving. ...more

I had the honor and pleasure of reading DUPLICITY before N.K. Traver received this book deal and was floored by the way the author is able to balance humor, suspense, cyber speak, and fully developed characters. The story takes twists and turns you won't see coming. You will fall in love with Brandon, the anti-hero who just can't get out of his own way, and Emma, the girl who may or may not be able (and willing) to help him. It will have you flipping pages and salivating for more. Cannot wait to ...more

Initial Impressions 1/24/16: 3 stars
This was much different than I expected! I think with the mention of "hacker", I had expected a lot more of the thriller aspect from a hacker vs the authorities kind of story and... well, I guess that was the story but it was largely taking place in a sci-fi world instead of in a realistic fiction setting. I think I was hoping for more of a feel like the movie The Net (90s Sandra Bullock at her finest) where the main character essentially gets replaced by a ne

DUPLICITY is an unexpected surprise of a read with a lightning-fast pace, a richly imagined virtual world, and a few mind-bending plot twists that will keep readers glued to the page. It is exciting and suspenseful and envisions a scary reality where technological and scientific advancements allow the tables to be turned on hackers in the most chilling of ways.

Brandon Eriks was sure he covered his tracks and that as a hacker he was untraceable. But when it appears as if he was hacked and that th

Why you should read it: This has been one of my favorite reads this month, and I definitely recommend it to fans of the twisted and strange. Brandon is a bad boy who uses his image to hold the world at bay, and uses his hacking skills to keep the world at arm's length. Our heroine, Emma, really sees him, which is why I think Brandon really connects with her. Now on to the plot! I think some readers will have a hard time suspending disbelief, but if you do it's a really, really intriguing concept ...more

Duplicity seems to be apart of a growing trend of cyberpunk books, a trend that I’m extremely excited about. Though I’m a fan of cyberpunk, Duplicity truly didn’t cut it and I was so disappointed by the plot and characters in this one. This novel is filled with lackluster sci-fi and romantic elements, plus it has a horrible representation of GLBTQAI+ and female characters.

I received this YA novel as part of first-reads. A big thank-you to Goodreads, N.K. Traver, and St. Martin's Griffin!

This book was a pleasant surprise from the very beginning. When I first started reading, I was afraid that I was missing out on something. I kept wondering who Emma was. This was cleverly written because Traver keeps the reader wondering about Emma and what her impact is on Brandon, the main character. Brandon is definitely a bad boy, and not one that caring parents would want any

Duplicity made me NEVER WANT TO LOOK IN A MIRROR EVER AGAIN!!!! In other words, this book was gripping, thrilling, scary, high-stakes, and utterly fantastic!

There are so many things to love about this book: Brandon, the protagonist, is such an unconventional character, and it is refreshing to read about a wayward, headstrong, hard-ass like him. (I imagine Brandon would be the sarcastic, multi-piercing, tattooed, slightly-nefarious cousin of the Weasley twins, shouting "Give her hell from us!") T

My Review: I have been extremely lucky in the past month or so to have had the opportunity to read YA novels with unique male protagonists. As an educator working with mostly reluctant readers, it is very difficult to find Young Adult books with interesting male leads that will keep teenage boys engaged. After having read The Tragic Age by Stephen Metcalfe and now Duplicity  by the brilliant N.K. Traver, it almost feels like I hit the jackpot.

Hmm. To put it bluntly, I didn't like this book. The concept was intriguing, but the writing felt much too amateur for me. If I was being harsh, this would get a one star, but it's a quick read and had some potential, so I'm going to be generous and up it to two.

This story details a teenage "rebel", hacker Brandon, who has fallen for a "good girl", sweet and innocent Emma, but this is complicated by the fact that his reflection seems to have taken on a life of his own and is attempting to steal

I'm sad to say this one didn't work well for me. First, I never really cared for Brandon. Although we do come to understand why he acts the way he does, he mostly read like a typical Bad Boy to me. I'm fatigued by that type of guy. I also didn't feel that connected to Emma, partly because she wasn't in a lot of the book. I thought she'd team up more with Brandon, but he spent the beginning pushing her away, and then she was out of the picture for a while. I just wanted more from her/their storyl ...more

I haven't read a lot of unique YA fiction lately. It seems everything on the shelves lately has its foot in some other story already told. Such is not the case with Duplicity.

Brandon is that guy that you see often and want to know more about even though you probably shouldn't, especially if you're a "good girl." Mysterious, tattooed, an apparent "bad boy," this seventeen year old is the truth to "there's more to a person than meets the eye." Hacking into bank accounts is just a hobby for Brando

I loved it! Everyone should read it. Need I say more? Okay ... I was curious to know how the plot would play out. Could Traver pull off the idea presented in the blurb? Yup. She pulled it off, and she pulled it off very well. I thought it was believable and creepy and awesome. The stakes escalated and the pace accelerated as the story played out, and I found myself reading faster and faster to see how it would all end. I look forward to more by Traver.

Review crossposted from Reanne Reads.

This was a pretty interesting book. I haven’t read a lot of this sort of techno sci-fi thing, especially not ones that seem to be YA, so it was a nice change of pace. The characters were sympathetic enough, and the main character’s flaws were in large part what the book was about.

I don’t think I even read the blurb before listening to this one. The cover and title looked interesting, it’s in a genre I like, and it’s read by one of my favorite narrators (MacLe

I had a love-hate relationship with this book. I HATED the first half and LOVED the middle and was okay with the end. Brandon is NOT a likable character an I'm fine with that. But he falls too neatly into the stereotypical pierced, tattooed, black-wearing "bad boy" role for me. I wanted more depth. More than just 'my parents are always busy boo hoo I'm going to be an ass for basically no reason'. Because yes h

Seventeen year old hacker, Brandon Eriks, a bad boy with multiple tattoos, piercings, dyed black, messy hair and an attitude to match, thinks he’s covered up his money-making hacking activities pretty well. Until one day he finds warning and personal messages on his computer.

From the moment that I picked up Duplicity, I was hooked and literally didn’t put it down until it was finished. I am writing this review immediately after reading it, and I must admit- my heart is still racing.

ARC received from St. Martin's Press as part of a Goodreads giveaway.

This engaging cyberthriller is one of the few YA novels I've read with a completely believable male protagonist. I like that he wasn't just foul-mouthed and obsessed with girls, the typical characteristics of many YA male leads I've read. Brandon is so very human, with more obvious flaws and hidden flaws. He's cynical, brash, and brazen, but under that he is hurt, lonely, misunderstood. He is terrified to care about other peopl

Very impressive. While I started this novel, a few friends and I threw out theories on what the title means in the way of the story, and what was going to happen. We even went as far as to search the meaning of duplicity in plural dictionaries. All of our theories were wrong. Not one of us got even close to getting it right. That is an impressive feat, because surprising and intriguing a reader is half the battle of writing a good book, and is extremely difficult to do in a world of “seen that, ...more

I truely think that's a record! In fact, he hasn't stopped raving about how great this book was and has asked to find more books by N.K. Traver.

I read this because it was on sale on audible. It was a fun read.

Bottom line is, if I wanted to live in reality and in things that could only happen there, I wouldn't read. It's fiction. I never need it to be believable. Make it crazy, unbelievable, outlandish. And that's what this was. I liked it. Fun.

It wasn’t too many years later Traver realized it didn’t matter what the job paid—nothing would ever be as fulfilling as writing. Programmer by day, writer by night, it was only a matter of time before the two overlapped.
