The Kill Switch (Tucker Wayne, Large Print)

From James Rollins and Grant Blackwood comes the first in an exciting new series featuring Captain Tucker Wayne and his military dog, Kane, ripped from the pages of Sigma Force for their first solo adventure.

The mission seems simple: extract a pharmaceutical magnate with the secret to a deadly bioweapon from Russia. But nothing is as it appears to be. A desperate call from Painter Crowe, director of Sigma Force, thrusts Tucker and Kane into a race to rescue Abram Bukolov from assassins backed by a shadowy Russian general.

Hunted and betrayed at every turn, Tucker and Kane must discover the truth behind a horror out of the past that can be weaponized to terrorize the modern world. It will take all of their skill, talent, and trust in each other to discover the key to stopping an ancient peril with the power to destroy the world.
