I am an addicted fan of Wen Spencer and her Ukiah Oregon series:
Alien Taste: Living with wolves as a child gave tracker Ukiah Oregon a heightened sense of smell and taste. Or so he thought-until he crossed paths with a criminal gang known as the Pack. Now, Ukiah is about to discover just how much he has in common with the Pack: a bond of blood, brotherhood...and destiny.
Tainted Trail: The sequel to Alien Taste (2001) sends Ukiah Oregon off on the trail of Alicia Kraynak, the niece of his partner Max's best friend. What appears to be an ordinary disappearance quickly turns out to involve alien invaders, the Ontongard (somewhat like the Borg of Star Trek: The Next Generation), and one of Ukiah's earlier selves, the feral Wild Boy of the Oregon wilderness. These contingencies immediately put Ukiah on his mettle, for he is actually the only fertile offspring of a rebel faction of the Ontongard that has been struggling for centuries to save Earth from universal infection and conversion into another conquered group-mind of the "orthodox" Ontongard. The battle against evil aliens is action-packed though relatively unsurprising, but Spencer's skillful characterizations, vividly drawn settings, and comic exploitation of Ukiah's deceptively youthful, highly buff looks make the romp high light entertainment. Fortunately, this isn't likely to be Ukiah's farewell performance.
Half-alien PI Ukiah Oregon is in bad grace with his moms, Jo and Lara, and his protecting pack. They are unhappy about Ukiah's engagement to FBI agent Indigo Zheng: the moms because, though Ukiah is a couple of centuries old, Indigo is too old for him; and the pack because he is marrying at all. Partner and mentor Max Bennett is on Ukiah's side, however, and that is critical when the routine tracking of a missing boy exposes Ukiah to a fanatical, malignant cult that kidnaps his son, Kitanning. The cultists have learned of the existence of the Ontongard, descendants of Ukiah's enemies who are still programmed to attempt to conquer Earth for their hive, and they are every bit as dangerous as those they call "demons," for they have acquired Ontongard chemical and biological weapons. Well-chosen everyday details as well as fire, murder, sudden death, and a lot of sex lead to an ending that resolves some of Ukiah's problems but leaves Earth's fate hanging fire for eagerly anticipated sequels.
Dog Warrior: On the run from a fanatical cult, Ukiah Oregon is surprised to discover Atticus Steele, a brother he didn't know he had. He's even more surprised when Atticus involves them in the traffic of an alien drug that could end up getting them both killed.
