My rating: 4 of 5 stars
The Kill Switch is the first in a new series starring Tucker Wayne and Kane whom we saw first in the novella "Tracker" and subsequently as a part of the Sigma Force team in Bloodline. Rightfully getting their own marquee, the odd pair of man and dog head up into their first solo missing for Sigma.
Tucker and Kane are best buddies, the know each other well and are living extensions of the other. They don't need nobody else in their lives. In Russia on a protection gig for a Russian business oligarch, Tucker is drafted by the wily Sigma boss Painter Crowe for a side mission to escort and protect a pharmaceutical tycoon out of Russia who is being chased by a Russian General who used to run Soviet Unions bio labs.
The hullabaloo is all about a ancient pest in the form of fungus or plant which has the capacity to either revolutionize the world or wipe it out depending on which way you use the pest. The discovery is too significant for it to fall in the hands of the Russians (who knows what havoc they may wreck with it) and since there is no counter agent or "kill switch" in military parlance, it becomes a issue of utmost importance that the Sigma Force protect it at all costs. The only fly in the ointment is that the path to the pest is known only to the Russian tycoon who is being chased by the Russian secret service.
Enter Tucker and Kane, the delta and the MWD. What I liked about this book is that Rollins and Blackwood spend time on the level of bonding between Tucker and Kane and how they are essentially so tightly coupled that they really are extensions of each other. Kane understands what Tucker wants from him and is trained enough to override his basic responses.
The book uniquely also contains a POV from Kane's perspective as he dives into the various caves and tight spaces based on Tuckers command. The reader is taken into Kane's mind, his senses and essentially made to feel what he feels in such scenes. It is a refreshing concept and the authors rightly using it sparingly to retain the effect of the POV switch.
Overall the book is a good read, nothing too outstanding, Rollins's background as a veterinarian comes through in scenes involving Kane and though process behind it. The plot twists are a bit too convenient and at some places the situation appears to be contrived to generate more difficulties for the lead pair. I would rate this book 3.5 stars rounded off 4. The blurb for the next book in the series appears interesting, but so many more interesting things available to read, I would say the next book will be spending some extra time on my waiting list unless it is mind boggling in its own right.
