This is a wonderfully written book, with a lovely writing style and flow that make it incredibly easy to read. 

The tone shifts ever so slightly as you work through the book, so gradually that you barely notice it until the big revelations start to come to the surface. Morton-Thomas also peppers through just enough hints of what's happening below the surface that all of the twists seem to fit, even when you're doing a double take at what you've just read. 
All of the characters are uniquely understandable, all of them interesting and flawed in a different way. The two POV characters in particular are written so well that you almost kick yourself when the final reveal so clearly highlights all the places in which their perspectives skew what you have been shown.

The best way to describe it is as a sort of anti-thriller. There isn't one big question, but instead the reader is left with more and more questions and it's almost impossible to know what the central mystery is exactly, and yet you're still left on the edge of your seat waiting for the big reveal when everything comes together. 

I'll definintely be looking out for more of Morton-Thomas's work, which is high praise given that this novel doesn't fit in with my usual fare. 

I received an advance review copy for free, and I am leaving this review voluntarily.
