Tempted By the Butler by Erin Bedford

Vampire Hunters beware. This human won’t be rolling over for anyone, not anymore.
Left stranded with Darren while her masters outrun the hunters, Piper has had enough of being a liability.
With a great new job, a new attitude, and surprisingly wicked right hook, Piper isn’t going to just wait around anymore for the hunters to destroy her life. If only she could find them.
Favors from old friends and deals with the devil lead Piper down a narrow and dangerous road. One that could save everything she holds dear or bring it all crashing down on all of them.
