In the tradition of the Navajo Code Talkers, the US Air Force initiated a Top-Secret mission called Project Oaktree. Eurasian red squirrels were genetically modified to create a super weapon: a spy incapable of detection, trained to fly, and who can gather intel in any location. In book 2 of the Acorn Squadron Chronicles, Flying in the Shadow of Death, Bushtail and the tiny pilots of the 999th Reconnaissance Drone Squadron take flight again. Stationed overseas in Afghanistan, the squirrel pilots and communication liaisons settle into military life on the front lines. Flying low-altitude operations in the Middle East brings new challenges, adventures, and tragedy. The squirrels encounter air combat, dangerous camel spiders, and distrust at home. When political games impact Air Force life, Bushtail finds out the real enemy may be closer than they think. Will Bushtail and his friends survive the threats from insurgents, wild animals, and friendly fire from within the Pentagon? Discover what happens next to the tiny heroes of the 999th.
