Bounty hunter Dakota del Toro always gets her werewolf. When she's almost fired from the Preternatural Control Team for bringing in a mark who tests to be human she knows something is rotten in Santa Fe, New Mexico. Her 1965 Beetle is stolen, and a werewolf ransacks her house looking for drugs she doesn't have. Determined to get to the bottom of it, Dakota enlists the help of Diego de Gama, all-too-handsome gallery owner and vampire revolutionary--who may or may not have designs on her immortal soul. Somehow, the disappearance of a teenage narco-princess seems to tie in to it all. Hot on the trail, Dakota is led into the mysterious world of Changelings, a counterculture who pretends they are were-creatures. It's all fun and games until someone loses their heart--pulled still beating from their chest. The heat turns up at a Halloween masquerade at Kama Luna, a nightclub for the things that go bump in the night. Ready to face a wicked witch of the Amazon and her whip-wielding consort, Dakota ties on her mask and straps on her guns. She'll show these beasties how she earned the name la Cazadora--or die trying.
