Under the Gun (Underworld Detection Agency Chronicles)

Quick thinking and loyalty have taken human Sophie Lawson a long way in the UDA - along with a healthy dose of magic immunity. But when her old boss Pete Sampson asks for help after a mysterious two year disappearance, she's determined to find out what high placed demon has put two ruthless werewolf killers on his tail. Of course, sucking up to her icy vampire department head and negotiating a treacherous interoffice demon battle are the kind of workplace politics that could easily get a "breather" way worse than reprimanded. And sexy fallen angel Alex is doing whatever it takes to heat up Sophie's professional cool and raise feelings she's done her best to bury. Too bad their investigation is about to uncover the Agency's darkest secrets...and powerful entities happy to sign one inquisitive human's pink slip in blood.
