This book really started great. The moments where the three main characters were introduced, their actions, and how they were taken out of their timeline were wonderful and exciting. Once all three were together, I ended up DNFing this.
I was really disappointed and hesitant to quit, but the dialogue between the three (and the other side characters too) was just imbecilic. The head guy of this whole project seemed to be a moron. The three main character's banter back and forth was elementary level (literally this: fighting over how to say the year 2111 either as twenty-one eleven or two triple one devolved into "my way is cooler" "no, my way is cooler" "no it's not, mine is" and so on). It was supposed to be played off as gallows humor to break tension in a stressful situation but it just played out as incredibly stupid and annoying.
The logic was bad too. At least the main guy didn't even try to explain the workings of time travel - "I don't know, the creator did it and didn't tell anyone, it has to do with a mathematical formula" so it avoided that. On the other hand, how other things work, or how they don't think they will affect things (or be able to survive) in the Cretaceous period where they are hiding out and other things are just laughable.
Not only that but the three main characters are basically god-like when it comes to fighting, apparently. They take on a dozen well trained soldier/guards, killing 3-4+ and hospitalizing the rest before they are put down with a tranquilizer. And the one, Ben, is notably not trained. It wasn't clear in how far I read but it sounds like he can just analyze things so well he just knows where to punch and kick at the right moments. Sounds like a X-Men super-power in what is supposed to be a [mostly] realistic [light sci-fi] book.
One more thing, wait, make that two. The writing is done in present tense. I didn't always notice it, but when I did, it was glaringly obvious. I don't know if there was a reason for this in this novel, but there is usually a reason why this is an uncommon method. The other thing, the chapters cover each of the three main characters and their point of view at the same time. It switches every paragraph or so. So it's like a non-omniscient narrator for Ben one paragraph, then switches to Safa's point-of-view, then the next paragraph it's from Harry's then the next paragraph it's an omniscient narrator overall, and it bounces around like this constantly. It's irritating to say the least.
I really wanted to like this. The premise sounded great. I just couldn't stand the writing.
