I'll start by mentioning the one thing that irritated me most about this book... it balances precariously on the edge of being more a serial than series. Perhaps I am being nice or I have reached the place when I read an indie book that mentions it is part of a series, I take it for granted that it is going to be a serial not a series and I don't get my hopes up. I did find that although it ended up on a cliffhanger, there was enough story and conclusion to at least squeak past the serial vs. series measure favorably.
That out of the way, this was a decent afternoon thriller. If you like mixing current events with some dubious yet in theory, plausible, medical science, grab a copy of this book! It is currently free if you subscribe to Kindle Unlimited. I was impressed enough by Mr. Adair to grab another couple of his novels.
