Something a bit different here.
An enjoyable read by a new author.
Thanks to netgalley and the publisher for my copy.
A worthy four star read.

Life turns on a dime and this book takes that idea and runs with it. Just one look turns Jim’s life upside down. I really liked the concept and through the author did a good job of developing Jim and his relationships in such a way that I felt very invested in him and what happened. Some lovely use of language here, too, which was nice.

I recommend this book largely for its curiosity value. It's a novel which refuses to be put in a genre pigeonhole.
Lee Coates launches into his debut with several stream of consciousness passages which give little indication of where the plot is likely to go. It's an innovative approach.
The horror when it comes is totally unexpected and brutally graphic and perhaps more so as it appears at this stage to have no human or supernatural intervention.
Suddenly relationships are thrown into turmoil: father and son, girlfriend and boyfriend; and the complexities of the plot are established.
I loved the total ambiguity of the ending and fates left hanging in the balance.
