A strange accident on the freeway, accusations of murder, and an encounter in the Idaho wilderness all propel Todd Clarke into a new friendship with a dog named Sparky. But Sparky is no ordinary dog, and there is more going on than Clarke could have imagined. A military commander he investigated for Aryan activity and links to domestic terrorism is after him, and he's not sure why until another chance encounter provides the answer. With Sparky and the help of his canine friends, will he be able to figure out the Colonel's plan and stop him in time? All Clarke knows for sure is none of it would be possible without the help of his Stray Ally.
