Blood on the Bayou — Stacey Jay

First came a terrorist attack. Then the mutations -- and Fey who had lived in harmony with humans turned deadly. Now most people hide behind iron gates. But those who are immune -- and those with enough courage -- can venture out into the Louisiana Delta . . . and a nightmare world of magic. NO GOOD DEED GOES UNPUNISHED Annabelle Lee, a Fairy Containment and Control agent with immunity to fairy venom, is once again called upon to help solve a murder deep in the bayou. But this one's off the books. Her ex-lover, Hitch, needs her help searching for a secret chemical weapons lab and an FBI mole providing it with human lab rats.Helping Hitch means certain interpersonal disaster with her estranged boyfriend, but Annabelle knows what it feels like to be a lab rat. Her new fairy-attack-induced paranormal abilities seem to have few negative side effects, but would that change if she stopped injecting herself with the mystery drug delivered to her by the even more mysterious -- not to mention ridiculously attractive -- Tucker? A man who can turn invisible at will, and who makes no bones about how dead she'll be if she reveals his secrets?As the murder investigation progresses, Annabelle quickly learns Tucker isn't the only one with secrets, and that the only things that cut deeper than a friend's deception are the lies we tell ourselves.
