Victory 'Vicky' Vaughn is Cerddorion (Welsh shapeshifter) and also a kick-ass demon hunter with a lot of survival skills, as well as one particularly dark mark that came about after her father's tragic death. She lives in Deadtown, and has a roommate who happens to be a vampire. Deadtown is where Boston's paranormals live. She's kept very busy with her job of exterminating demons from people's lives. She gets paid well, and is even considering taking on an apprentice--a teenage zombie with a knack for trouble.
However, when a Hellion arrives in Deadtown, her life becomes one big mess. See, she's got a past with this particular Hellion, and she's determined to do whatever it takes to stop him from executing his plans. With so much on the line, she finds herself in one problem after another, leading to an outstanding conclusion.
I know I've already said it, but I loved everything about this book. Even the subplots and love interests--I believe I've got a soft spot for Daniel--added to the overall story. And the worldbuilding's amazing. Pure brilliance.
Yep, this is probably going to make it on my fave-urban-fantasy-series list. :)
