Superb combination of science, factual evidence (real events, data),trauma and the unknown variable.It ended far too soon. The actual solution was a cop out. Mcbride takes us into frankly frightening realms and then plays the easy explanation card. That didn't gel well for me, especially after the complex build up.It had an Fallen aura about it (film D. Washington). Eerie and bordering on unbelievable and yet somehow also being plausible.I really wanted to know whether there could be a scientific or psychological link.Mcbride is certainly an author to watch out for. I would also like to commend his research into the thought process of victims in the situations described in this story both during and after the events in question. I received a free copy of this book via NetGalley.
