Having read and liked the set-up novella (Tracker), I was pumped to read a real novel starring loner Tucker Wayne and his faithful sidekick, the military dog, Belgian Malinois, Kane. The highly improbable story (it is fiction, after all) involves the race to rediscover a virulent bioweapon. A Russian scientist wants to defect, and Wayne/Kane are sent to assist, finding themselves in a battle with a crazy Russian old-school warmonger and his hired assassin. Along the way, there is treachery and a race to develop a "kill switch" to combat the potential devastation of the bioweapon. I would have liked more of the segues from Kane's perspective, which were better done in the novella, because the thinking was less developed, as you would suspect from a dog (i.e., Wayne is "pack.") Perhaps this is because Rollins wrote the book, rather than co-authored?

If you can suspend disbelief and like non-stop action, go for it. ( )

I really enjoyed reading this book, 4 stars.
Since Kane is so awesome, he gets at least a 5! ( )

This is the first of a series involving Tucker Wayne and Kane whom we met in Rollins' book, Bloodline. It is part of the Sigma universe, but only as a spin-off. Sigma plays a critical role in this book, but we encounter few of the normal Sigma characters.

Instead, our two heroes are Tucker Wayne and his Belgian Malinois who have to extract a Russian botnist who has made a discovery that could, as in many of Rollins' novels, save or destroy the world. Also like Rollins' novels, they travel all around the globe, from the tip-top in Russia to southern Africa. However, there is much less jumping around between multiple plot lines and multiple continents.

Other standard Rollins' devices includes caves, people refusing to die, and dogs on their haunches. ( )

This was much better than the second book in the Tucker Wayne series, "War Hawk," which I reviewed earlier. More action, and not as predictable.|

My only complaint in both his series thus far, is that I wish he would involve Kane, the dog, more in his stories. He seems to involve him more in "War Hawk" then here, but "The Kill Switch" had more action and more twists in the story. ( )

Kill Switch is filled with action-packed adventure. Many twists and turns keep Tucker and Kane busy in this thriller, while they search for an organism that can 'kill' a deadly contaminant from the beginning of life, accompanied by an unlikely team. ( )
