Quick and easy read- but not necessarily a good thing.  The concept had me intrigued, and I will say I did keep turning the page to know more,  but I think that’s largely because I was waiting for something to happen.  This novel is largely filled with the inner thoughts of our characters rather than action and plot.  The writing was a bit lacking and was over narrated and repetitive at times.  
The last few pages revealed the “ah-ha!” of the novel, but lacked believability due to a couple of factors.  
I’d say this is a 2.5 for me.  Enjoyable enough, but I’m not sure it would be one I would recommend to others with confidence.  
Thank you to NetGalley and Storm Publishing for the ARC in exchange for my honest review.
