The Devil's Work (Mel Goes to Hell series #1)

Tired of torturing damned souls, Lucifer decides it's time for a career change. As the new CEO of the HELL Corporation, Luce Iblis is ready to take over the world, starting with a city he's sure even angels haven't heard about: Perth, Western Australia.
Until an angel appears in his office, vowing that the Lord of Hell will never win.
Hell hath no fury like a devil scorned.
And Lucifer's about to raise Hell.
