Good book, albeit some too-large time jumps

The 3rd book in the trilogy does a pretty good job of wrapping things up - I didn't give it 5 stars because I thought there were a few too-large large gaps in the time frames. There were gaps of several years in some spots and I think there was more that could have been done in those areas. To get the full impact, I'd recommend reading the 1st 2 books in the trilogy or if you've read them, re-reading the 2nd to get up to speed on the characters.

A good editor could have given a better timeline to this book. It leaps around quite a bit in its reminiscing.

There's a lot I liked about this book, and a lot I found tedious.  There's plenty of action and twists & turns that kept my interest.  Some of the plot is plausible (such as intense rivalry between company presidents) but many plot details are not (there are so many "incidents" it's a wonder the characters could function at all!).  The book is long, and although there were exciting parts, the book could have wrapped up sooner.  On the Kindle forum, there was some "controversy" about a particular sex scene and whether the book should have been tagged pornography.  I didn't find this scene to be either erotic or repulsive; in fact, one of the characters called it "laughable" and I found that to be an accurate description.  There were also some editing errors and I can usually overlook them.  I do, however, get irritated when a wrong character's name is used, and I did find that one time in this book.

But, for all its shortcomings, I still give this book a four star rating because the pace was exciting, it kept my interest, and I simply enjoyed it.

I will admit I was expecting the book to be more of a "what if" than it ended up being; in reality, it's more about time travel than what would happen if JFK had survived. On the other hand, in some ways that made it refreshing. There's a slightly predictable Bad Future when we return, but it's not really about the "what if", so it works.

The only problem is that the book drags in places, especially when it's time to kill Oswald. Still, the writing is very good, and I enjoyed the story very much.

Business first: I was given a copy of this book to read and review.
Time's Adversary is a well-written novel that reminds me of early science fiction such as Brave New World, the Martian Chronicles and maybe even 1984. But then, about half of the way through the book, things change and become much more 'modern' in context. The old plots are pushed away and new ground is explored. Unlike some previous reviewers, I found messages in this story, warnings, perhaps of what we COULD do in the future, and the potential outcomes.

I liked the book. I think it is definitely worth reading. The jumpiness between venues was odd and, to me, a bit awkward, although I understand what the author was trying to do. I believe a bit more polish on the "transformations" could help smooth these out.

I was impressed with this book.  First off, I thought Baxter wouldn't be able to keep up the H. G. Wells writing style, but he deffinately pulled it off.  Also, the demented plot takes the time traveler to fantastic places spaning epochs that are increadibly imaginitive.  The main thing I found annoying was: Why the heck is this genius time traveller so DUMB?!  I mean, I would have figured out some of the stuff that he was baffled by, and I don't think I could build a time machine if someone gave me some Plattnerite!

First and foremost, this is definitely a book worth a read. I did have problems with parts of the book. Certain twists in the book in the end either did not pan out or became convoluted. Without spoiling the book for any of those who have not gotten a  chance to read it there were parts that I couldn't put down and other parts that left me scratching my head. I however do look forward to a sequel novel with the hopes that the "rules" of how the time travel device becomes more developed.

Although generally not a sci/fi fan, I do love time travel books.  This one starts out terrific.  The beginning, when the protagonist is a child, totally works and gets you right into the story.  Unfortunately, I felt it bogged down a bit after that until about one half to two-thirds into it, when it zipped right along through to the end.  In fact, I read the last third of the book in one sitting.  Technically, the writing was very good.  I felt the characters could have been filled out a bit more, especially the female character.  There were also times where it was difficult to have a willing suspension of disbelief, a necessity for a time travel book.  Nevertheless, definitely a time travel book worth reading.

Pretty good, but a bit disjointed and "rushed" in places

I read this when it came out and really enjoyed it except for two things:

1. The ending felt a little rushed.
2. I don't think the time skipping really added anything, and I had to flip back a few times to remind myself of the dates. I'm sure that won't bother most people, but it's a pet peeve of mine.

That said, I'll definitely pick up more books by Erin Morgenstern!

I am tempted to paraphrase the legendary reviewer of the Poseidon Adventure who reportedly said "ship sinks, but not fast enough". Or maybe that was from Mad Magazine. Anyway, this review could be simply, " Moon breaks up, but not fast enough."

Seriously, the first part of the book is quite interesting and the characters likewise. This, in spite of the improbable technical question of whether the moon could actually breakup, as told in this scenario. At the point where the moon breaks into several chunks, the story is compelling and fast paced. However, as time goes on until the human species nears its end, it does tend to drag.

I was over half way into the book before I realized the significance of the title. that is because it doesn't come into play until that point.  The issue of the characters' issue is actually another of the bones I have to pick with the premises advanced here.  The act of stimulating cell division with one gamete, (the egg) that may have been genetically engineered, is perfectly plausible and has been done with animals. That you could ultimately have "races" based on inherited characteristics from each of the egg donors, does strain credibility. In the second or third generation the scientist creates a Y chromosome, so now there are men. Since the men will likely mate with the women who are not their siblings or cousins, it is not explained how the descendants of each original female parent would be clearly different races after 5000 years.
Also, I just have to throw in the fact that the women who were too old to have any or many viable eggs certainly could have grown babies with eggs donated by other women. We see this currently with women around 50 and older who have babies using egg donors.

This book is incredibly long (although I read the ebook and don't even know how many pages it is. I think it's over 800. It is truly a saga, but a saga that drags on and on and pretty much falls apart in the last third or half of the book. In some ways, there are several books rolled into one. Some authors solve the saga length problem by writing multiple novels, e.g. Robinson with the  Red, Green and Blue Mars books. this option seems to be very common with science fiction today.

By the end, I found some similarity between Seveneves and H.G. Wells', Time Machine. You definitely have the diggers as Morlocks. the spacers are probably the time travelers or maybe the Eloys. Along with everything else, it is flat out impossible to think that a dry, decimated earth could be Tereformed in only a few thousand years; Especially one well stocked with plants and animals.
In short, I would recommend this book to die hard long convoluted story fans. Why did I stick with it? well, I did want to find out what happened.

Nigel Walden begins to experience "unhappenings" in his teenage years. They are a prelude to a life thrown into turmoil by humanity's primitive dabbling in the field of time travel in the 21st and 22nd Centuries. Somewhat frantically paced at times, occasionally difficult to follow, with a main thesis that seems a bit improbable, "Unhappenings" is not a perfect book and certainly not a happy one. Nevertheless, I could not give it less than five stars. Impossible to put down. I would like to see a book by Aubry in this vein which fleshes out some of the episodes and leaves the reader with a sense that something good and productive might come about through carefully controlled experiments in time travel.

Overall, this was a very good book.  Stylistically, as expected, it reminded me greatly of 2001, so if you liked 2001, you'll probably enjoy 2010 as well.  What is interesting is to see how much Clarke sees the world developing over the 9 years since 2001.  One area that I didn't enjoy was the change in geography.  While not a spoiler, 2001 has a lot of book take place en route to and in the Saturn system.  However, because the 2001 movie took place in the Jupiter system, this book assumes that the events that occurred in 2001 in fact occurred in the Jupiter system, which is very inconsistent.

A little long winded ...but all in all a good book

Timebound was a decent read, but could have been better. I loved the premise, and haven't read a time travel story in a long time, so I'm glad I read this one.

The characters were interesting, but a little unbelievable. For example the love interest believes Kate's story much too readily. It would have been more believable if he had gone through more disbelief, like thinking her "proof" was some sort of magic trick, slight of hand type thing. But instead he immediately believes she can time travel. It's just not likely.

I imagine that time travel with various timelines can be difficult to write, but I felt the author did a good job with this. It all made sense to me and I was never confused about where I was, when I was, or why this new timeline was different. And I loved how the serial killer/Chicago World's Fair was weaved into the story.

I found the story well written on a technical level, but there was, at times, too much infodump in the dialogue. This made the story drag a bit for me sometimes. I also wish the actual time travel had happened earlier in the book. The first two-thirds seemed slow because of this, but the last third was worth the wait.

I would recommend this book to time travel fans and those who are interested in the 1893 Chicago World's Fair.

This is a very good book, long before it became a movie. It's too bad that lame casting, adaptation, and apparently promoting the movie as a teenfest sullied the book's reputation.

In any event, the book is well done time-travel. There's good pacing that keeps the pages turning, fun characters, and a good setting.

I struggled with how to rate this book. I really enjoyed reading it--I wanted to keep reading, and never considered stopping. The concept of time travel (won't spoil it by giving details) was fascinating and different than anything else I've read in that genre.

However, a couple of things really bothered me. Characters didn't seem realistic. One of the main characters experiences a tremendous loss early in the book, and it hardly seems to affect her. Every few chapters, the character seems to remember the loss and briefly get sad before moving on. It doesn't makes sense for it to be shock, as this character is just acting way too normal. Another character fits that old novel stereotype of "ex-Special Forces dude who can do practically anything."

The second annoyance was the long periods of exposition, especially when explaining time travel. There's got to be a way to get through the explanations faster, and get back to the action.

The story is very compelling, and because of that, I enjoyed the novel a lot. The writing, however, lacks depth and realism.
