Unison Spark is a very unique story and a great debut novel from Andy Marino. I really enjoyed this book and I look forward to reading his future books.The world of ESC and Unison is unlike any I have read about. Unison is basically the king of social networks and it is scary to think that someday we might come to that point. I really think the world that Andy Marino created is his strongest point. I loved reading about it and how it got to where it was.The characters, on the other hand, were the weak point in the book. I really liked Ambrose but I did not like Mistletoe. It seemed like she was trying to be something she wasn't and I couldn't connect with her. Sliv was also weak. He seemed like a very interesting character but he was barely there. I would have liked more of his story.The plot of the book was another of it's redeeming qualities. It was very fast-paced and interesting. It was pretty much non-stop action. I also liked that it was multiple POVs so you could see things through both character's eyes.Overall, Unison Spark is a great dystopian sci-fi that I think will appeal to a lot of people. Also, it seems like this one will be a standalone. I felt that everything tied up very nicely in the end.
