Temping is Hell (Entangled Edge) (Necessary Evil)

Temping is Hell by Cathy Yardley

WORST. JOB. EVER.

Kate O'Hara can't wait until this temp assignment is over. The woman who hired her is a psychotic pageant queen, her coworkers are convicts-turned-clerks, and it's so boringly corporate it makes her skin crawl. Even her sexy-as-sin boss, famed billionaire Thomas Kestrel, isn't enticement enough to keep her there. Once she makes enough to pay off her bills, she's out. Or so she thinks...

WHAT THE HELL?

Next thing she knows, she's accidentally signed over her soul. Literally. And she's discovered Thomas's real mission: to kill thirteen bad guys in one year, in order to get his—now his and Kate’s—souls back.

 IT'S NOT JUST A JOB. IT'S A MISADVENTURE.

From learning to boost the morale of some paper-pushing demons to navigating her way through blood-red tape, Kate has to work closely with her super-hot supervisor and get her flaky act together, before somebody clocks her out—permanently!
