You don't need to know much about high tech security to understand what's going on in this technological thriller. It reads more like an action film with the "chase" scene starting from the very beginning. Our MC goes on the run from the police determined to solve her husband's murder right from the beginning, and doesn't stop until the very end. Rather unrealistic, you'll have to suspend all of your disbelief.

I guessed the perp at the half-way mark, and it was so obvious (mainly due to the lack of developed characters) that I thought it had to be a red herring. Sadly, it was not and the thrill of figuring out the mystery wasn't there with this latest book from Ware.

I also could have done without the repeated, graphic descriptions of the murder victims body.

The ending was infuriating for me.

Zero days is a thriller in which a woman’s husband is brutally killed leaving her to find the clues and solve the mystery to why he was killed. Full of twist and turns.

Ruth Ware has done it again! Zero Days was an engrossing mystery that I could not put down! From the first chapter I was hooked and this fast paced mystery did not disappoint! I loved all the tech parts and even learned a few things!

Zero Days by Rth Ware delves into the world of hacking and online crimes. Married couple, Jack and Gabe, are hired by businesses to test their security systems. Companies then use their feedback to strengthen their operations. After a successful night of penetrating a business, Jack arrives home to find her husband no longer alive. She has no idea what's happening but soon realizes she will have to run in order to save her own self. She then begins a cat-and-mouse game with not only the police but also the perpetrators of the crime against her husband. Lots of action and secret unraveling keep this book moving right along. Read and enjoy!

Ruth Ware’s books are so good it makes me want to cry. Her books are like an addicting good piece of cake and you just keep wanting more. You can’t STOP wanting more but you need it, you feel it deeply, you want more information, more clues, and you want it now. She only gives you tiny morsels though. But the crumbs are so delicious you’re willing to sacrifice sleep, family time, anything just so you can finally get that big slice of cake.

This book was no exception. It was gritty and felt like a spy thriller throughout. The beginning few chapters will hook you and next thing you know you’re along for the wild ride. Her writing is masterful the way she paces each chapter through a design of dialogue and narration. Intense scenes will have you reading faster and you can feel your heart rate elevate, slow creeping chapters will have you waiting for the other shoe to drop and have you feeling anxious.

This book went a little more towards tech and spy-based thrill than Ruth Ware has done in the past but she did a fantastic job (of course). This book gives this underlying feeling of espionage the whole time that makes you want to know if the feeling is just a feeling or if you’re on the right track.

Another wonderful read by Ruth Ware. I would consider myself a huge fan of anything Ruth Ware. This particular read was somewhat different from her other books. I really enjoyed the content, the characters, the complexity of the story, and the story development. I didn't feel it was easy to predict what was going to happen next in the story. I read the entire book in only two days. I would highly recommend this story to anyone who enjoys Ruth Ware. This release is a true thriller.

I have read all of Ruth Ware. I enjoy most of her books- some more hit or miss than others. I wouldn't consider this one my favorite, but it was a fun wild ride. Ware usually writes slow burner stories that have complex storylines. This basically had one storyline from one character's POV without much complexity. We actually never learn who the killer is at the end and the author emphasizes that the WHO isn't important but the WHY. You have to suspend your belief a bit with the why, but we do get a conclusion. Just not as satisfying as past Ware novels. I overall recommend the book- it is fast paced and you can fly through it. Just know going in that it differs from her normal style of writing.

I am a huge Ruth Ware fan and have read every single one of her books. I was so excited and fortunate enough to receive an ARC of Zero Days. I couldn’t wait to dive in! While it had the normal twists and turns from Ware’s previous writings this book left me with wanting more. Still a great read that I will recommend to others!

“The only thing they’re lacking is a motive. Don’t give them one.”

“Because what does love need, except someone to love back?”

Woah. I FLEW through this book. It has been a minute since I have read a book that was that fast paced and that anxiety inducing. What a fabulous and realistic story! I recommend going in blind because I did and it made each twist all the more surprising.

Ruth Ware is an auto-buy author for me and this book just reinforces why. This book was written so well I could swear I just watched a movie. What a ride!

Thank you to Netgalley, Scout Press Books, Gallery Books, and the author for the ARC in exchange for an honest review.

Lately I have been kind of let down by her books. The IT girl felt too predictable for me. This was the same. I have just felt mediocre about them. The woman in cabin 10 is one of my favorite books. Maybe it's just something that cannot be replicated. i will still keep reading her books and hoping for another woman in cabin feeling.

Ruth Ware never fails to keep me on the edge of my seat and this book did not disappoint. I loved that she went a similar direction as she did with "One By One" utilizing technology for this thriller. The story follows a couple who help improve the security of companies until one day, our main character Jack comes home to find her husband dead. This triggers Jack to question who can she trust as she goes on the run to find out who killed her husband and why. The book is heartbreaking at times as Jack gives up hope, leans on the memory of her husband to get her through, and pushes through challenges due to her drive to prove her innocence. Another great book from Ware and, as always, I'm excited to see what she write next.

<i>Thank you to the publisher and NetGalley for this ARC.</i>

I would like to thank NetGalley and Simon & Schuster Publishing for the eARC of this book. I initially received and read this book before it came out, but my life got super complicated and it took me a hot minute to be able to sit down and finish my review (sorry).

First off, I love Ruth Ware and have read most of her books. Zero Days is not a typical Ruth Ware book, as in, it’s not a locked-room style mystery. I would actually consider it more of a thriller, with definite Mission Impossible or Oceans 11 vibes, with a little The Fugitive mixed in.

I really liked the book. The plot was good, and the pacing was very fast, and the characters were very likeable. Jack and Gabe, the main characters are “penetration specialists” (I honestly didn’t know that was a real thing) trying to break into security systems to test their strength. Except it goes very badly. There was a lot of action and a twisty plot, and it kept me engaged the whole time.

I read a lot of horror, mysteries, and thrillers and I definitely enjoyed the genre switch-up by Ware. I wouldn’t say it’s my favorite of her books, but it was definitely good! And book club worthy!

Jack and Gabe have a company that finds security weaknesses for companies. Gabe finds the tech weaknesses and Jack finds the physical weaknesses. One night things don't go as planned and Jack is arrested. When her identity is finally verified it is late and she is distracted and gets lost heading home. She arrives to find Gabe dead at his computer. As if things can't get worse the police begin to suspect that she killed him. She didn't do it and has to find a way to prove it. The only way is to walk away from the police but this puts a target on her back. The more she finds the more confused she is. Who did this? Who can she trust? Will she survive long enough to figure it out?

Ruth Ware, Ruth Ware! I either LOVE her books or they are “ehhh”.

• There was a lot of fun and interesting parts to this book but I’m personally not a fan of the “on the run thrillers/suspense”. So take my review for what it is!

• I loved Jack’s job. That was so interesting and unique and her “set of skills”. Such a different concept

• There is sooo much technology written in this book that I think would interest a lot of people.

• I didn’t love the whole “on the run” and her journey through that. I am just not a huge fan of that type of plot so I didn’t find it super entertaining.

• overall it was a nice read and I will always read Ruth Ware!!

I typically like Ruth Ware novels and appreciate her writing style and ability to tell a good mystery. This one differs that some of the another books I’ve read by her and although I still liked this novel, I took off a star for predictability. I like good twists and turns to be sure, so although I enjoyed reading this, I want to be more surprised at the ending.

This book is gives “Mission Impossible” vibes, full of action and thrills that will get your heart pumping. I found myself trying to read faster at times to get through some intense moments…lol. This was an interesting read overall minus me figuring it out, but if you like action packed novels, this one will do the trick.

I'm a Ruth Ware fan for sure and this one had several twists I didn't see coming. I was on the edge of my seat by the end racing to figure out the conclusion. Great thriller read

Ruth Ware is a skilled writer who always keeps my attention. Her pacing is spot on. Zero Days kept me engaged from the first page with its complex plot and characters.

Another great ride from Ruth Ware. This time it was much more action and I felt so sad along with the protagonist.

A security tester finds her husband dead and her the primary suspect and will go to amazing lengths to find those responsible and bring them to justice.

So much heart and such a strong set of characters. I love that this book lets you feel the love the main character has for her husband and her family, it's so raw and fulfilling to the story.

I thought that Jack was a very strong character who was very resourceful and determined to find the killer. The story didn’t hold my interest but that was a personal thing not being interested in techno security. This one was just ok for me. 2.5 stars.

I just want to start by saying I loved Jack's character. She was fierce, determined, and didn't take any crap from anyone. Add her crazy amount of resilience and you have the makings for an extremely strong female lead. While this book was different than what I expected, I found myself rooting for Jack, even as I was appalled by her crazy choices. A quick, easy read that would be a perfect read any time of the year.
