Rating: 3/5 
 ***Minor spoilers*** 
 Etta has spent almost her entire life playing the violin. She has spent hours and hours each day honing her skills in the hope of turning that talent into something. All that gets cut short when, during a performance, she hears some sort of strange earsplitting noise that nobody else can hear, and messes up in front of everyone. When she and someone else who claims to have heard the noise goes to investigate, she finds her violin instructor dead, and she is pulled into - somewhere. But where? When she comes to, she's on a boat somehow, dressed in unfamiliar clothes. She was pulled through a passage into a different time, and is being brought to a man who requested her presence. But why? Soon, Etta will find out how much she is involved in this world, and what she has to do to save her own time. 
 I had high hopes for this novel, mostly because I had really enjoyed The Darkest Minds. While my ratings as that series went on dropped, I figured this book would still be good. And it was. It just wasn't as good as I had hoped for. I think my main problem was the lack of feeling. Etta is on a race to save her own time from changing completely, she's on a time limit, she's being chased, she doesn't know who her enemies are - but where's the sense of desperation? I felt like I was just floating along in the book, and there was no sense of excitement, terror, anticipation, or anxiety. I feel like the thing that evoked the most feeling in me was Etta's relationship with Nicholas, which in my opinion shouldn't have really been at the forefront of what caused a reaction in me. I also felt that the book was unnecessarily long. It felt slow at some points, and strangle fast at others, as well. 
 Aside from my issues with the plot, the characters were pretty good. I think I liked Nicholas more than I liked Etta, mostly because he was the rational one and because I felt like he had the most character development. I thought Etta was a bit annoying, mostly because she liked to act like she knew what was going on, but in reality she had only just been introduced to this whole new concept a few days ago, so other people (read, Nicholas) always had to pick up after her mistakes. I did like the environment, though, since this book does travel through various eras and we get a glimpse of different time periods. I love that sort of stuff in books, so that gave me some enjoyment. 
 Overall, I liked the book but didn't love it. The concept was interesting, I liked the characters enough, and the historical aspect was nice, but I thought the plot was lacking. I wish we got more emotion out of Etta, considering basically everything she knows and loves is at stake. Aside from my few problems with the book, I'd recommend it if you're into sci-fi, or if you're interested in reading another Bracken novel that's veered in a different direction in terms of genre.
