I'd forgotten the synopsis of this story when I picked it up to read it, so I was initially surprised to find a dual narrative, from Etta, our violin prodigy thrown into a world of time travel and Nicholas, our (POC! WOO!) sea faring Captain trapped in 1776. The story starts off with the terrible moment in Nicholas's past when he loses his brother, before taking us to Etta who's waiting for her violin recital. 
 I love me some time travel and this has lots and lots of it, jumping from country to country, time period to time period. The way the time travel works in this is very cleverly explained and makes complete sense too, I haven't seen time travel done this way before. Nicholas and Etta are thrown together by Etta's relative, and forced to search for a mysterious object in order to save Etta's mother. 
 There is one big thing in this that I did not like and it's also the reason I dropped a star. I thought (or maybe madly wished), that the wholeinsta-romance rubbish of 2010 was over and here it is again. The romance between Nicholas and Etta was so, so forced it was uncomfortable and I couldn't get into it. It should have built up slowly and had them realise that they liked each other during a major event in the last quarter of the book. I would have been so, so much more invested in it. 
 The ending had just enough big reveals and questions for me to want to run to BookDepository and pre-order it, sadly for me it looks like I'll be waiting until next year! And it's only March now. *ugly sobbing*
