The Demon Of Renaissance Drive

For one of Hell's preeminent succubi, life should be sweet...and it is, if you like sulfuric air, political minefields, and crashing boredom. After six thousand years the succubus Annabelle finds relief from her dull life in the companionship of a damned soul named Harry, until the Kings of Hell decide they disapprove of Annabelle and Harry's bond.
Unfortunately, even escaping to Earth isn't enough to keep the pair safe. Somewhere between dodging a dangerously inquisitive psychologist and fighting Satanists out for Harry's life, Annabelle realizes running is no longer an option. She must return home and make a stand.
Whether she survives or not, at least she isn't bored anymore...
