Truthfully, I have no idea how I feel about Dissonance. In the terms of full disclosure I read this book after I read two books I had been dying for that were fantastic and nothing could live up to that. So I don't know if my uncertain feelings are because this book was a 'rebound' book or if I really wasn't as in love with it as I hoped I would be. I mean Dissonance wasn't a bad book, but I didn't feel like it was a great book either. 
 The story is about Del, a girl that gets to travel into parallel worlds because she is what is known as a Walker. With every choice a person makes a new world, or Echo, is formed and Del gets to navigate them and figure out which ones are stable. But Del has never been one to follow the rules. And when her long time crush starts popping up in all of her Echoes and noticing her in her real world, the Key World, Del is even less likely to follow the rules. When things start changing in both the Key World and the Echoes, Del must figure out where she stands and what's important to her. 
 Part of my problem with Dissonance was the pacing. It's a long book. No getting around that. It's a lot of pages with a lot of information and newish terms. Some of the stuff is very dense so it makes it hard to focus and pay attention. But that wasn't the problem. The problem was that nothing seemed to be happening. It took about 3 quarters of reading before I was like, 'oh, something just happened'. It made reading a struggle at times wish was disappointing. On the surface the premise is really good, but all the buildup and background and unfamiliar words made it harder to get through. 
 Not that the whole book was bad. There were some really strong parts. The interwoven story of the characters was a part that I really enjoyed along with the different family dynamics. Del's family was interesting. Addie was a know-it-all, and her parents were workaholics, and her grandfather was somewhere there kind of holding the family together in a way. The way that this dynamic reshaped and changed as the story progressed was a really good part. And when things started to happen, they really started to happen. Whether it was Simon, Del's crush, and his evolving part in Del's life or the mystery surrounding the instability in all the worlds, things definitely sped up. Enough to make me want to continue on with the series? That remains to be seen.
