Abandoned as a child, Ukiah Oregon was found running with a wolf pack. Now considered one of the greatest trackers in the country, this private investigator puts his nose to the ground to track down missing fugitives. When he crosses paths with a criminal gang called the Pack, Ukiah discovers just how much he has in common with the Pack.

Ukiah Oregon, half-man and half-alien raised by wolves, is hired to track a missing hiker. When her trail grows cold, Ukiah discovers the woman has actually been kidnapped. He then stumbles upon another mystery related to the unsolved disappearance in 1933 of a legendary wolf boy. The hiker's abduction may hold the key to Ukiah's past.

Ukiah and his senior partner, Max Bennett, are just returning to Pittsburgh after the events of Tainted Trail. Before they even land, they have a new tracking job—to find a boy missing from his backyard. Driving straight from the airport, Ukiah and Max start another adventure, one that will involve kidnapped children, a drug-dealing biker gang, a UFO cult, a hostile federal agent, the Pack, Max’s new love Samuel Anne Killington, Ukiah’s FBI lover Indigo Zheng, his two adoptive mothers, and his infant son, Kittanning.

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.
