"You know what a 'zero day flaw' is?"


"It's a flaw in an operating system that isn't discovered until it's too late. And by the time it's found, you have ---"

"Zero days to fix it."

"Yes, exactly."

The Addie Webster kidnapping made headlines - Governor's eight-year-old daughter disappears without a trace! Now it's eight years later. Governor Webster has become President Webster, struggling during his second term, and dealing with a strange terrorist group. Then suddenly, Addie Webster is back,

Zero Day is entertaining, but it's also clearly written by someone who has almost no idea how computer hacking, domestic terrorism OR the political world works.

(We're legitimately supposed to believe that a teenager without any professional training can hack the White House server without getting detected? And in five minutes, at that? COME ON.)

Also, Jan Gangsei has a definite telling vs. showing problem throughout the book. It made for some seriously awkward sentences.

Finally, the book ends

A really well-crafted, fun, twisty YA thriller. Think Homeland meets The Gallagher Girls.

Zero Day had a lot of layers that drew me in. I love watching crime and drama television shows and this book encompassed all that. Huge shows like Scandal have really sprung up a new found interest in political thrillers for me and after falling in love with The Fixer earlier this year, I just knew Zero Day would be another hit.

Addie is our focus of the story. In the beginning she is kidnapped at a young age just to escape many years later to r

REVIEW: I read this in one sitting--so amazing! I requested this book for review when I read the blurb on NetGalley, but I was absolutely hooked from the very first chapter. This reminds me of John Grisham or Tom Clancy for teens. I love how the story allows readers to make realizations right along with Addie and Darrow. I also love how it was told with flashbacks so we could gain insight on what happened to Addie for eight years.

There is some romance, but the ma

This is a fast-paced YA thriller which I read in no time. There are many thought-provoking layers in the plot : Stockholm syndrome,cyber espionage and security, civil rights , family bonds, living with guilt and coping with loss .The characters are appealing and well developed; Jan Gangsei makes it easy to understand them and their feelings .

I found the book too short , though. I wanted to know much more about the characters and their background . I wanted such a good plot to be developed furthe

Last night I finished this book, and gave it 4 stars. Then I slept on it. Now I'm thinking it deserves no more than 3 stars. The plot of this book was interesting, and had me intrigued. However, a girl is missing for 8 years and everyone kinda treats her like she was away for a month. This story was supposed to be adventurous and exciting...yet there was a whole bunch of stupid drama and the romance was so stupid. The characters are flat and boring too.

It's a quick, fun read. Just not realistic

Ugh. I rarely give one star ratings. I can usually find something I like, but it didn't happen with this one. I tried. I actually liked the way this one started. It made me feel how much I've missed reading this genre. That feeling didn't last long though. It was replaced by excessive eye rolling. So much of this didn't work for me. The dialogue. The plot. The kidnapping. The hacking. The world building.
The characters. The clueless-ness. This all created a giant plausibility problem. I didn't

At a Glance:

ZERO DAY was an exciting, political mystery/thriller that had me guessing from beginning to end. Though there were times you have to suspend disbelief, the overall fast-pace and mystery make up for lack of plausibility. If you're looking for a fast, fun, and twisty read, I think you'll really enjoy this one.


I love the cover! I think it may have a more serious tone than the book actually does, but I love that it gives off the political vibe.


There's quite a bit of action!

I love a good scandal book where there is secrets, lies, and everything inbetween. Man I feel so privileged to have read this ARC. Once I started reading I could not stop reading it. It reminded me of so many TV shows I watch that I could not quite put my finger on which show it is.

In this story we meet Addie Webster who has been kidnapped as a child and held in some compound. Her parents who are high profile grieve for their daughter and continue to look for her for a while. As time goes on Add

Holy crow! I mainlined this fast-paced political thrill ride in a matter of hours! The storyline--lips are sealed because HOLY SPOILER, BATMAN--is beautifully executed and messed with my mind all the way to the end. Loved this.



Five glorious stars.

I listened to this audio book, and it was actually quite enjoyable.

The reason for the 3 star rating is that at times the plot was ludicrous, silly even--in places, and the writing could be quite cliche'.

That said, the overall plot was original, and I enjoyed the characters.
This is actually listed on Amazon as a YA book, which I didn't realize when I downloaded it from my local library. That said, about 1/3 of the book is told from an adult's pov. (There are quite a few points of view.)

I loved this. I thought it was very suspenseful. I couldn't decide if I trusted Addie or not for much of the story. It is a book I would definitely recommend to my middle school students, boys and girls.

I enjoyed Zero Day - I think it was definitely a good thing that the politics were so minor, since I'm feeling very political these days!

What worked: characters - loved Adie and felt like the portrayal of her brainwashing was fairly well done. I liked the difficulty she had trusting her parents or believing in them.
- I like the narration a lot

What could have worked better:
- I think it required a lot of belief in situations I just can't see going through. President's daughter returned mysteriou

Obviously, there’s been a bit of an absence on the blog. Blame the Louisiana bar exam for that. They don’t call it the fourth worse one in the country for nothing, ya’ll.

The good thing is the test is done, so my free time has improved for the time being. I’m sure that could change though. This review will probably be a quickie though for various reasons.

I read or should I say partially read Zero Day about six or seven weeks ago. I probably shouldn’t even be writing

I'm a big fan of Homeland, especially the first couple seasons. I also love some good political thrillers (as hard as they are to find), and Zero Day may be the closest thing to a Homeland-style political thriller for the YA set I've seen in some time.

Addie was kidnapped from the home of her politician father eight years earlier, and it became one of the most well-known kidnappings in history. She then reappeared eight years later, just as her father was elected President of the United States.

This was just...okay. It's a quick read--or it SHOULD have been, but it didn't hold my attention so I found myself putting it down an awful lot. There's a lot of mystery and intrigue, but a lot of political stuff needs a lot more explanation to make sense. (view spoiler) ...more
Dec 27, 2015 rated it it was ok
This book was full of interesting ideas that were never really fully developed. It left a lot of loose ends open - so much so I thought it was series, but according to the author it's a standalone "with potential for more." Which honestly just makes the lame cliffhanger even more frustrating. I think the book would have been better if it focused on less perspectives and cut out a couple of the extraneous storylines and just really focused in on Addie and Cerberus. ...more

It was refreshing to read a genre that I don’t normally read! This was a political thriller about cyber terrorism and family secrets. I really enjoyed it! It was totally creepy at times, and really suspenseful!
There were a few unnecessary cuss words but other than that, a clean and entertaining read!

Zero Day is a realistic fiction/thriller novel by Jan Gangsei. Overall I enjoyed the novel form its detailed sentences and character development, yet this book really lacked the thrill part with not much action. I still like it and would recommend to young adult readers.

I am not a big thriller fan, but the premise alone drew me in. I was curious about Addie, what had happened to her, and who she was now. I also am a sucker for stories about the president’s kid and happen to adore a Secret Service romance every now and again. The problem is I have a hard time finding them [note: there is no Secret Service romance in this book] [note note: but that’s okay!] and finding one I enjoy.

So let’s talk about this book. I was hooked right away. The first 150 pages worked

ARC provided by NetGalley in exchange for an honest review.

Zero Day is a unique YA political thriller with a hint of romance. It's certainly unlike anything I've read in the YA literature lately (I read a lot), and for that, I give it high praise. Jan Gangsei has managed to break some YA molds here, combining politics and romance, family drama and thriller, and twisting characters around to leave the reader honestly intrigued and a bit confused (more on that later).

Thrilling, well-written, and suspenseful, Zero Game pulled me right into the drama and kept me guessing at every turn.

Ms. Gangsei gave me just enough tidbits of information that I could make some educated guesses, but not enough for the story to become in any way predictable.

Addie is likable and interesting -- I felt for her and sympathized with her and the ordeal she went through. I really liked Darrow, caring, brave, sensitive, loyal -- he is almost too good to be true, as far as teenage boy

As a child Addie was kidnapped, everyone thought she was dead until she reappeared while her father was president. Darrow was Addie's best friend before the kidnapping and from the start of Addie's return he knows something is off in Addie-land. As the story progresses readers learn that, while away, Addie was indoctrinated by a terrorist fringe group with plans to bring revenge to the United States.

As I write this, I am sleep-deprived, because I was up til all hours (okay, 12:30am) because I couldn't stop reading it.

The synopsis makes it sound really good, right? But it's actually season one of 24 good, the kind of book I cannot stop reading until it's over.

I spent most of the book not entirely sure who to believe or who the "good guys" were. There are so many layers and everyone has secrets and everyone seems to be's the kind of book that really does demand precedence over wh
