Dante Valentine is not too keen to wake up one night to find her lover missing from her bed. He's been a long-term frustration, as perhaps befits a 'fallen' inhabitant of Hell and Lucifer's one-time right hand man. Dante, to help her career of bounty hunter and death-dealer to the undead extraordinaire, has been researching as many aged, coded texts about demonology as she can, but the one chap who can help her most - the demon she calls partner, Japhrimel - refuses to explain anything.
