To stop her sadistic grandfather, Saul, and his band of time travelers from rewriting history, Kate must race to retrieve the CHRONOS keys before they fall into the Cyrists’ hands. If she jumps back in time and pulls the wrong key―one that might tip off the Cyrists to her strategy―her whole plan could come crashing down, jeopardizing the future of millions of innocent people. Kate’s only ally is Kiernan, who also carries the time-traveling gene. But their growing bond threatens everything Kate is trying to rebuild with Trey, her boyfriend who can’t remember the relationship she can’t forget.
As evidence of Saul’s twisted mind builds, Kate’s missions become more complex, blurring the line between good and evil. Which of the people Saul plans to sacrifice in the past can she and Kiernan save without risking their ultimate goal―or their own lives?

About the Author
Rysa Walker is the author of the runaway hit Timebound, which was the 2013 Amazon Breakthrough Novel Award Grand Prize winner, and the novella Time’s Echo. Walker grew up on a cattle ranch in the South, where her entertainment options included talking to cows and reading books. On the rare occasion that she gained control of the television, she watched Star Trek and imagined living in the future, on distant planets, or at least in a town big enough to have a stoplight. She now lives in North Carolina with her husband, two sons, and their golden retriever, Lucy.

I found Time’s Edge to be even better than Timebound. There were more interesting time jumps, less learning how to time travel (which affected the pacing of the first book for me), crazier experiences including a mass death of a small town and a lynching. The plot became deeper, the characters more three dimensional and I really grew to like Kate’s character a lot more in this as she grew into a young woman.
Kate is on a mission, she is one of only a handful of people who know that the present she is currently living in has been altered. Once upon a time her grandparents worked for Chronos, whose main job was to observe important historical events for the true history. That was until her grandfather Saul decided he wanted to control history and create a future where he held enormous wealth and power. With the help of Kate’s aunt Pru, Saul has influenced key moments in time creating a religious following called Cyrists. When Saul blew up Chronos in the future he left about a dozen time travelers scattered throughout the past. Now Kate needs to find them and convince them to give her their time travel keys so she can stop her Grandfathers evil plan.
I really liked all of the time travel explanations and showing how it affects different people. Sometimes it took a few minutes to sometimes wrap my head around certain situations but I caught onto the rules that Rysa Walker used for her story and I think she lived within those rules pretty well. Sometimes I get a little nitpicky on sci-fi stuff like this but it was done in a way there wasn’t anything glaringly wrong.
"You know, this would be a lot easier to get used to if you had to go back to you TARDIS if whatever before you disappeared."
Another aspect I really like about the story is the actually in the history of it. I enjoy when Kate is trapesing through different historical times and the little tidbits that are thrown in. The time in Georgia in 1911 and 1938 I found especially interesting. The culture of the era was different and I thought that the research was done really well with FDR’s campaigning, the attitude of the town towards people of color and even how different terms were created.
“Arrests? For What?”
“Necking in the canoes. Canoedling, some of them all it.”
I give him a skeptical look. “Why make out in a canoe? There are people all around them. It’s not very private.”
“People in the other boats are doing the same thing, so they aren’t gonna pay you any mind. In a few years, when there are autos everywhere, the backseat will put these canoe vendors out of business, but right now, those boats are the most privacy you can buy for a dime.”
I HATE LOVE TRIANGES….Raise your hand if you also hate love triangles.
BUT…..I didn’t at all mind the love triangle in this book. It will probably still break my heart into a million pieces later on as most freaking love triangles do. That said I totally accepted in this story because: Kiernan met Kate in a different time line, one only he remembers. In that they were together for a few years and completely in love. He still has all of those feelings even if she can’t remember ‘his’ Kate. Kate fell in love with Trey in the time line she remembers, but they are trying to get to know one another again since he doesn’t remember her when the last time line shifted. (I know that seems a bit confusing but really it is done far better than I explained it here)
”I’m not saying you don’t care about Trey. I know you do. You might even love be in love with him, although I don’t like thinking about that possibility. All I’m saying is you have feelings for me, too. And don’t give me any crap about my inflated ego. I’ve seen you in love with me before, and I still see something of that in your eyes. I’ve tried to tell myself it’s just wishful thinking but it’s not..."
So even if you aren’t a fan of love triangles don’t let that deter you. There is plenty of time jumping around to different time points, trying to figure out what Saul’s ultimate plan is and how to thwart him, who can we trust for sure and who is really the enemy.
The ending is a slight cliff hanger but in a super exciting WOW I want to read the next book right now kind of way. So if you like time travel, historical fiction or just a good solid story go ahead and jump in the space time continuum is fine.
It's 2:30 am now & I really must get some sleep, so I'll be keeping this short (for me).
My suggestion is to start at the beginning with book one "Time Bound" & sit back & enjoy yourself. There is an inbetween book called "Time's Echo" and then this last book that I just read is "Time's Edge". It was so fast paced that I am still trying to calm down so I can continue writing this review. I suspect there will be another book in a year or so. Which makes it super hard to wait. But I will.
Maybe night time reading isn't the best idea when your reading about the Chronos Group (individuals who are historians that have a device they use to jump to certain spots in time & space -what these books are about). But I couldn't stop myself. I bet you won't be able to either. God help the people that have to get up early and go to work after spending a night reading. Luckily I'm retired and don't have to worry about that. ha ha
If you are a fan of mysteries and intrigue then this set of books is for you. Even if you don't normally read sci-fi or time travel type genres I bet you'll love these. There are all sorts of twists and turns through-out all the books, each leading you deeper and deeper into the characters and towards an end. But we still don't find out what that 'end' is - not even in this book. So there has to be more coming. Right?
I'm not sure what age group these books were initially written for. They may have been created for young adults like the Hunger Games. But it doesn't matter in this case either because from young adult to the elderly reader, the subject matter is very interesting and entertaining. There is a lot of historical truths in these books. Yes, this is a work of fiction; but the author treats us with many real places and real events that have taken place in various times in our country.
If you are a parent who's teen is reading this series there is very little (if any) cussing and sexual content, which is nice. Sometimes it seems that authors mess up their whole book by putting lots of cussing &/or sex into it when it really doesn't advance a character or the plot - it's simply gratuitous.
Having never read any other reviews of this series of books I don't know what others have said. I imagine some go into great detail about the characters - especially the main one - a teenager named Kate. I rarely discuss specifics in my reviews simply because I think people should be able to read the book and be surprised as they go along instead of already knowing what's going to happen. So don't look for that from me. I merely say how satisfying the book was to me (or not) and a few things about it that might encourage or discourage a person from reading it for themselves.
However, I will say this about Kate: she is tenacious in her determination to get the job done. She keeps her femininity intact & is not at all rough around the edges or boyish. Her courageous attitude & intelligence may tend to get her in trouble at times as she is a bit too eager & impulsive & independant. But that is often the way teens are. They rush into things without thinking it all the way through. So that's why she needs another character to balance her out & slow her down with rational & more mature ideas. She gets plenty of help in that department. So now you know - Kate is spunky & cute as the girl she is. But she's more than that and she proves it to everybody.

The plot was so so so dull and it's all filler.
