This really is only for the WWI history buffs out there. It is all adventure and escapism, but interspersed with a little too much of the author showing off his knowledge and research. The fact that two of the characters are professors and one is a military weapons fanatic gives him ample opportunity to do this.

The main protagonist - the Jack Christie of the title - is a bit too bland and whingey to really catch anyone's interest. And we all know, if you're not interested in the protagonist...

So, yes, well written with a certain amount of interest - but only really for those with an existing interest in the history of the First World War.

Day of the Assassins is a realistic fiction novel by Johnny O'brien. The book is about Jack and his best friend, Angus and they become embroiled in a plot to use a time travel machine to prevent Archduke Franz Ferdinand's assassination, thus preventing World War I from taking place. Jack learns that his father has built the machine with some fellow scientists. Only to complicate it further, a rival group of travelers want to prevent Jack's dad and his cohorts from changing history. Jack and Angus end up back in the Austro Hungarian Empire just days before the assassination.
Many readers will love Day of the Assassins, because it's full of action-packed battles, where the heroes seek out an escape from certain death repeatedly. This book is definatly not for younger kid becasue of all the violence that takes place in the book.
I gave this book three stars because it was good but could be a lot better. for starters, too many characters are introduced only to be killed or to ride off with no other mention. I wasn't satisfied with the explanation of the rival groups of travelers. They didn't explain them in the right way insted they weren't notice as a threat until Jack was in danger. All in all, I think that this book was a good book but could be so much better.

This book, Day of the Assassins, is a good historical fiction book. As most historical books go, this one is most appealing to those who enjoy history. This book talks about the Assassination that happens right before WW1. Jack and his friend Angus were wandering through his dad’s work which led them to a time machine. Angus finds himself in time before ArchDuke Franz Ferdinand got assassinated. He must decide what he must do, stop the assassination and alter the future, or let them kill him to make sure the future is not harmed. The book is quite slow to start. It takes around 40-50 pages for stuff to get interesting, but the plot is good. I rated it 4 stars mainly because of the plot. I am not much a history person, so this book isn’t as intriguing for me as it would for a history lover. I would highly recommend this book to someone who likes history, but I would be more reluctant to recommend it to anyone else.

Going back in time to stop a major historical event like a war from happening may seem like a noble thing to do on the surface, but for Jack Christie and his friend Angus, altering the past can have adverse affects on the future. This book reads a little like "Back to the Future." It was an entertaining read.

I have always been a fan of books about time travel. This book did not disappoint. I like how the author not only has the protagonists travel back in time, but he also has them considering the ramifications to any alterations that they may make.

I love history but I am not the intended audience for this book either. I think young boys would probably really enjoy this book. I enjoyed the idea of the book and thought it was an ok book but I wasn't blown away.

It did seem a bit rushed in spots that I felt more time should have been taken and dragged where I thought it could have shined.

I’m going to come straight out with it an say that my history knowledge is embarrassingly bad. When I was a school, history was the lesson for catching up on sleep, exploring the artistic merit of the doodle and praying something exciting would go past the window. Needless to say I dropped the subject as soon as I could but when you’re a kid you’re looking toward the future, it’s hard to get excited about what happened hundreds of years ago.

That’s why I was so pleased when I read Day of the Assassins. Yes, it’s a time travel adventure story but it’s one that really focuses on the history, bringing the world to life just as it was on the eve of World War I. This is just the kind of book I missed out on as a kid, the kind that would have had me glued to my chair in my history lessons because I’d actually been there with Jack Christie and experienced it all. I knew absolutely nothing about WWI before I read this book, the reason why it started has always been a head scratcher for me because Europe looked very different back then. By the time I’d reached the last page, however, I was an expert on the subject and the ingenious part of it is that I didn’t feel like I was learning anything while I read. I thought I had been on a brilliant adventure but actually I’d had a crucial lesson that I’d missed out on as a kid and more importantly, the excitement of history for me has increased hugely. Johnny O’Brien has taken the dull lesson and transformed it into hours of excitement, making it utterly relevant to modern kids who are more used to films and computer games than sitting with a book and learning.

Overall, the story is well forged and the characters convincing, although I think it’s probably suited a bit better to boys – and I don’t mean for that to sound derogatory but it is very action-centric. Again, I don’t mean for that to make it sound like it’s devoid of emotion because it’s anything but. Jack has to face some pretty horrendous moral dilemmas that I struggle to solve even now, having thought about it for a long time. Do you stop the event that caused the First World War and save millions of lives but in so doing completely change the future? Or do you sit back and let it happen, knowing full well the suffering that your inaction will inflict on countless people? It’s pretty heavy stuff that really adds so depth to the story. The great thing is that Johnny O’Brien gives the reader enough background information about the First World War as the adventure unfolds that you can make up your own mind about whether stopping the assassination of Archduke Ferdinand would have changed much. It seems there was so much tension in Europe at the time that if it hadn’t been that that sparked the war something else would have. There is that great sense of powerlessness for Jack Christie that makes him even more believable and even more admirable for doing the right thing.

Definitely one for the adventure lovers and one for those of you who didn’t pay attention in history!

When the publisher e-mailed me asking to review this book I didn't hesitate! I love history in books and this seemed like the perfect way to put it. Jack and his friend Angus find a time machine, the Taurus, and are thrown back to World War One. Think of it as a modern adventure in history!

The author has developed some really good ideas in this novel, I really liked how he threaded the brilliant ideas together. The whole aspect of the time machine is ingenious - you can only go when the little light is on (to show it has signal) and you can't come back when the light is off either. Jack and Angus' whole adventure is suspenseful - will the villains triumph? Should they intervene with history? Will they change the time-line events forever?

It is a face-paced book that is suitable for all ages. Everyone will enjoy it - children and adults alike! I liked how it is also an educational read too (sorry guys!), but we learn in a such an exciting way it is entertaining. I realised at the end of he book that I actually learnt a lot, and before I knew nothing about World War One!

In some stages of the book I was slightly muddled-up about where they were, and in small occasions I found it a little slow - but that didn't happen very often. There is plenty of action, and in some cases I see that the author had to do certain things to make it work.

This book is perfect for boys, but me being a girl I also found it very enjoyable! I am not sure if I speak for all girls, as I am a slight tom-boy! The introduction at the beginning from the author is very good too, all about Choices. He writes about how one little thing can change history, as we learn at the end of the book. I am also very lucky to have a guest post from the author similar to this on the 5th September, so come along (free advertising, lol) and maybe that will tempt you even more to read this brilliant book!


RATE: 3.5/5

Jack and his best friend, Angus, become embroiled in a plot to use a time travel machine to prevent Archduke Franz Ferdinand's assassination, thus preventing World War I from taking place. Seems like a crazy plot, doesn't it? Well, that's exactly what happens in Day of the Assassins when Jack learns that his father has built the machine with some fellow scientists. Only to complicate it further, a rival group of travelers want to prevent Jack's dad and his cohorts from changing history. Jack and Angus end up back in the Austro-Hungarian Empire just days before the assassination. Should they help prevent it or make sure it happens?

Many readers will love Day of the Assassins, because it's full of action-packed battles, where the heroes eek out an escape from certain death repeatedly. I was intrigued by the question--Should we change history if we have the ability to do so? Just as Jack must decide the answer, the reader will also ask himself the question. I can see where some would be tempted to prevent evil from happening, but I also can see the opposition's point of changing one event will start a trickle-down effect, changing many events and lives.

Personally, I don't think the story lived up to the promise of its premise. Too many characters are introduced only to be killed or to ride off with no other mention. I wasn't satisfied with the explanation of the rival groups of travelers, nor with the description of the formation of the VIGIL organization. Granted, this is the first book in a series, I just don't know that I'm curious enough to read book 2.

My grade: C

Day of the Assassins is one of my "have to read" books, but I have to admit it wasn't anything like what I expected. I avoided it for a long while thinking it was just another war story, but in fact it's sort of a Harry Turtledove for teens (Turtledove writes almost exclusively historical fantasy books, sort of playing what if through the ages....what if Germany won WWII, what if we lost the Revolutionary War, etc) The main character Jack finds a time machine (which was the first I knew I was in a science fiction novel) and he's caught between two warring factions who both own time machines.......one wants to change history by stopping WWI, and the other believes that changing history could have other more devastating consequences so we should leave it alone. Now that I think about it, it kind of reminds me a little bit of the Warlock series from Christopher Stasheff too......although most of the adventures take place on another planet many of the actual adventures involve stopping anarchists and other enemies of democracy from changing the history of Grammerye, and thus the universe as well. If you haven't read any of Stasheff's novels, you need to read them.....they are AWESOME......but back to this book......ahem......it was pretty good, lots of action, lots of historical references, and lots of flitting back & forth in time.......I think there will be a definite audience for this book unfortunately it'll have to be through booktalking, the cover to this book sucks and there is no book blurb on the back......

Jack Christie lives with his mom in Scotland; who knows where his father is. He left when Jack was four years old. Jack is now 15 and enjoys school (sometimes) and playing Point-of-Departure, a WWI video game, with his best friend Angus. After a series of strange events – Jack’s dad sends him a history book for his birthday, Jack keeps dreaming his is in a foxhole facing a German soldier, Jack and Angus discover a hidden workshop in his basement, the school janitors try to shoot them, and their history teacher appears in a photo of the members of the Black Hand – Jack and Angus embark on a time travelling adventure that takes them to 1914 just before the start of WWI. Will they stop the assassination of Franz Ferdinand? Should they?
This is a fast paced adventure with twists and turns at every corner. People are seldom who or what you think they are. I generally don’t like time travel novels – I find the whole idea just too contrived. But this one (although still not believable) was fun and exciting to read. Teens should love the fast-paced adventure. The only issue I have is there’s just a bit too much history. In an effort to explain the politics of the Balkans leading up to WWI accurately, the story bogs down sometimes. Other than that – good fun, lots of action. There are sure to be more in the series. In fact, the next one takes the boys to London, 1587, where they have to save Queen Elizabeth I.

This is one of those books that I recognize as a good book but that I just could not get into. Because I recognize it as such, I would still recommend to a certain group of people, likely pre-teen or teenage boys.

The main character, Jack, is very likable, with a good head on his shoulders and a positive sense of self. His best friend Angust rubbed me the wrong way for the first half of the book but started to win me over as his maturity progressed throughout the novel.

The conspiracy/secrecy aspect is well explained and makes the impossible sound quite reasonable. For the most part, the conflict is smoothly introduced, but the storyline becomes somewhat trite during the heart of the VIGIL/Jack/Jack's father scenes. I wish that the character of Jack's father had been explored in greater depth, as I believe this would have rounded out the plot.

Johnny O'Brien explains in great detail the types of weapons used during World War I and effectively integrates the historical aspects of the war and the plot of the story without coming off like a textbook.

Overall, the story was enjoyable, and though it is not one of my favorites, I would recommend it for YA males and anyone interested in historical action/adventure science fiction.

I wanted to like this one more. In fact, I was hoping to love it. I love history and love the premise of time travel in my fiction. Jack and his friend Angus are somewhat unlikely time travelers. Though, in a way, they've been preparing for it to a certain degree. Jack has a decided interest in a video game, "Point of Departure" about World War I. The game has levels, of course as you'd expect, and players can try to change history, etc. Angus enjoys the game, too. And one day while they are playing they discover a secret lab of sorts that they guess belonged to Jack's absent-father. They tell one of their teachers about it, and, of course, he just happens to be in the now. Turns out the teacher and Jack's father both know about the oh-so-secret invention of a time travel machine. Anyway, the two boys happen to be in the right place, right time to go back to 1914...and there are good guys and bad guys from the present and past after them. I liked the premise of this one better than the actual story. I'm not sure if it was just my mood, or, if it is a weak story. I liked it well enough, I definitely wanted to know what happened. But, I was hoping to like it more, I was wanting to be wowed.

One of those books you'd never buy on-line - but browsing in a bookshop, it takes your interest. The story is set in 1914 in Sarajevo where Jack Christie and Angus, two young boys, get caught up inadvertently in the plot to assassinate Archduke Ferdinand, setting off the Great War. However, Jack and Angus have come back from the future, knowing that the event will change European history. Should they intervene or not? Can they?
The book begins with the boys playing a computer game based on WW1 and trying to move up through its different levels. In the games, they manage to stop Princip from carrying out the assassination - which changes the course of world history. However, the game can't cope and the boys can't see the outcome at the next level as a programme is missing. Through a series of strange events, they confide in their teacher who brings them into a highly secret Government project on time travel. The story rattles on well - and brought me back to reading books in my early teens. I didn't expect to enjoy it as much - but it was great. Loved it. Never heard of the writer before or since. The book is lovingly produced with good photos and maps (at least in the hardback version I had). Brought out the teenager in me.

In the first instalment, Jack and his friend Angus not only discover the time machine, they are transported back to 1914, to try and stop the assassination of the Archduke Franz Joseph and therefore stopping World War I and changing the course of history. Jack discovers on the trip why his dad left him - he is working for the revisionists. On the trip Jack realises that he needs to make a decision - does he stop the assassination and change not only history but his own existence, or does he let the assassination happen?

Exciting, enthralling adventures., X-box meets HG Wells. Re-enacting what they have learnt in the computer game as they are transported into earlier times. The author provides a great journey through history which will hopefully provoke a genuine interest in major events that have shaped the world as it is.

At first, I didn't know if I would of liked it or not. But then when I started to read it some more I got more into the book. Personally I really liked it, and I do recommend it to anyone thats looking for action along with some history. I would recommend it because I'm not much of a book guy and I was intrigued by this book. It's never dull, and you can learn about history in World War II as well. I liked this book because even though I dont read very much I still enjoyed this book because it is meant for teens and I am a teen. I would recommend it to other teens because its not kid friendly but its a bit lacking for an adults book. I gave it a four out of five because it was a great book, but it can get confusing in some parts. I had to go back and reread a couple pages because there are so many characters, and it narrates from all there perspectives.

This book is pretty good, if you like history and reading about World War one. There is a good amount of action going on throughout the story. It goes into description on lots of things, such as military weaponry and other miscellaneous objects. I wasn’t sure how this book was going to turn out, it seemed very interesting in the beginning, then got kind of boring, then interesting again. The book becomes interesting after the first couple chapters, so hang in there if you’re going to read it.

I can’t really say anything about the plot line because there might be spoilers, but I can say it does have a lot to do with World War one. It’s a mix between modern times and the World War one era. All in all it was a good book but it had so much more potential than what the author exercised.

I have very mixed feelings for this book, some parts (especially the ending) literally made me gasp and other times I was beyond confused and slightly bored.
Spoilers ahead!

Let me explain myself, starting of with the good parts. I loved the beginning and ending of the book. I loved how it came full circle and te game they were playing in the beginning became what they experienced in the end it made me smile that such a small detail in the beginning could have such a large impact and I love when books include things like that.

However, to be able to enjoy this book I feel you already need prior knowledge about ww1 and guns and all that jazz. And I'll admit, I did not making some parts very confusing.

So in conclusion, if you are a history lover particularly the first world war period this book is perfect for you. And if you're not like me, it's still an enjoyable read!

Day of the Assassins is a book about two boys who go on an adventure to the year of 1914. They time travel back to 1914 on a mission to prevent World War I from happening. They have to do this by preventing the assassination of Archduke Franz Ferdinand. They encounter many issues along their journey and that is what really makes this book interesting. I thought that this book was a good read and kept me most of the time highly engaged. Based on what I have read, this book is more for the people who like action and adventure books and also people who like books with a lot of hi-tech technology.

I'm definitely not the books intended audience (though I do have an interest in World War I). It's an interesting enough time-travel book, but not up to the usual standards of genre. It doesn't handle the question of causality or the very important question of how to handle modern day technology in the past.

I wish I had a lot of good things to say about this, but I don't. The action is slow coming, the time travel aspect rough, and the alternate history idea neat but not handled great. I can't honestly tell if this was a problem of the book not being what I wanted or the book not being what it should have been.

Good time-travel action adventure book for younger teen boys- two boys are sent back in time to stop the assassination that sets off the horror of World War I- but when they get there, they begin to wonder if that's the right thing to do, as it will change the course of history...

Absolutely brilliant. The best book I've ever read!
Note: Some people are reviewing this book with scepticism, even though they are not in the target audience. This is nonsense! For any 9-14 year old, this book is perfect, and fits in the history course too!

For some reason this book took me forever to get though, but I did enjoy it. I actually am hoping it will do well and there will be more in the series.
