I've read a few AG Riddle books before and while I enjoyed them, they didn't wow me but i have to say this one changed all that for me. I finished it a few days ago and I am still thinking about it, trying to get my head around it all and unravel the knots that this book tied me up in. Time travel stories make my head hurt, but I love them. I loved all the plot twists in this one. The middle third of the book was a little bit like something out of a Michael Critchton book Jurassic Park book and was a nice side plot from the rest of the story which I'd class as more of a techno-mystery. I am keen to see what AG Riddle writes next.

Thank you to Netgalley, the author and publisher for an ARC of this book.
