As always with this imaginative and intelligent author, I found this book to be an excellent, original, read. This particular book felt almost like a book of two halves - brilliant interest and action, then very techie with a lack of action. Because of this, I did become a little unsure about how I would feel by the end, but then things all came together and I was left with satisfaction.

This may be a big book, full of sci-fi/speculative fiction in the tale of Alan Norris dealing with the loss of his wife and the raising of their daughter suddenly seeing a specific set of numbers whenever his tinnitus flares up and where that leads, but it is a wild ride with shadowy figures, murder, and a hunt to find answers that may end up saving the world. And I was hooked the whole time. This book balanced the sci-fi tech and the human emotions/characters well. Alan was a character easy to root for, strong, willing to help others despite the hardships of losing his wife, being a vet with a missing leg, and raising a daughter with her own difficulties. Add in a bit of Greek mythology, a race across the world unseen and a group of people willing to do the right thing and experts needed to save the world and you too will be sucked in! Plus I am always a sucker for tech that takes you to another place, in this case Labyrinth via immersive tech, how it can help, but also a darker side if it goes too far. Besides being a sci-fi thriller, it also brings up good questions that can be applied to the real world in how far we should go and when it might be detrimental to the human race. I am really glad I got the chance to read this and I am definitely planning on reading some of A.G. Riddles other books because if they are like this one, they will be great sci fi thrillers!

At times when reading this book I felt quite overwhelmed by what I was reading. I can understand why it took the author a lot longer to write it than he expected. It is such a complex read, that takes you to places and times and scenarios that you can’t image, but in another way it’s all too plausible. I’m not very tech savvie so felt a bit bewildered at some parts, and up until about 50% of the way through the book I wasn’t sure if I’d be able to finish it, but I also knew I had to find out how it all came together. It was a glimpse into our future but I still needed to know what happened to all of the characters, particularly Alan and Riley. Thanks to NetGalley, the author and the publishers for the opportunity to read and review this book.
