Atticus Steele is en route to Cape Cod when he rescues a stranger from death at the hands of a religious cult—and is surprised to learn that the man he’s saved is Ukah Oregon, his long-lost brother. Ukiah’s membership in the Dog Warriors— a paramilitary biker gang—gives him the ability to repay the favor by assisting Atticus in an undercover assignment to purchase an elusive new designer drug.
 
What Atticus discovers—and can’t believe—is that the mysterious drug is an alien intoxicant specially attuned to the brothers’ shared alien biology. When the religious zealots threaten Ukiah’s life again, Atticus must learn to trust the Dog Warriors and accept his own origins if he’s to have any chance of saving his brother’s life…and his own.
