The Blurb: When Kate Pierce-Keller’s grandmother gives her a strange blue medallion and speaks of time travel, sixteen-year-old Kate assumes the old woman is delusional. But it all becomes horrifyingly real when a murder in the past destroys the foundation of Kate’s present-day life. Suddenly, that medallion is the only thing protecting Kate from blinking out of existence.

Kate learns that the 1893 killing is part of something much more sinister, and Kate’s genetic ability to time-travel makes her the only one who can stop him. Risking everything, she travels to the Chicago World’s Fair to try to prevent the killing and the chain of events that follows.

Changing the timeline comes with a personal cost, however—if Kate succeeds, the boy she loves will have no memory of her existence. And regardless of her motives, does she have the right to manipulate the fate of the entire world?

My review: I found this book on amazon or .99 cents and was impressed by how good it was. I can’t summarize much of it because I don’t want to give anything away. The plot unfolds kind of like Orphan Black, it’s much more fun to watch/read with no clue what you’re going into. I can say the world building was excellent, the plot thoroughly thought through, and the moral dilemmas that came up about whether or not people should or shouldn’t exist and which timeline was correct were very interesting. I loved the main character. The only thing I didn’t care for was the insta-love (at least every character involved was likable) and there’s a bit of info dumping followed by demonstration which could have been cut since we’re immediately shown what we were just told. But neither was done over the top, so neither bothered me much. And the info dumping was realistic. When you’re getting taught how to do something new, you get told how to do it a lot and then you get to try it. So it’s hard to get that balance quite right.

This was a great book, reminded me a lot of Ruby Red. You should read it.
