Little Sister
This is a great read, beginning an arc within the series featuring the Enforcers, "Guardians of the Wolves". It begins with the kidnapping of one of the Willow Bend pack humans, Amelia Sullivan, whose sister Shiloh was lead in a previous book. Amelia, angry with her little sister's defiance of the rules and being rewarded for it, moved to Los Angeles to attend culinary school. She's snatched off the street only a few weeks after her arrival, tortured, starved and near death when she's found by Enforcer Mitch Jackson.
Mitch is a lone wolf groomed and recruited by Julian for the Enforcers, where he works with military precision and dedication. With help from a tracker he locates where Amelia is being held and enters the abandoned warehouse to find the bodies of humans from the various packs, and a barely alive Amelia. Injured in the battle with her guards, he takes her to his cabin in the Sierras to recover as an ice storm hits, isolating them without electricity or phone service. It doesn't take long for Mitch to realize Amelia has been given "the bite" and that away from her alpha and without a mate her chances of surviving the change are slim. There is a good chance she will go mad and he will have to put her down. But Mitch is determined to get 'little sister" through to the other side, alive and well, and back home safely to her pack. Hopefully, that's what she wants, too.
