Möjligen Glen Duncans 2003-roman Jag, Lucifer.
Från Amazon-länken:
The End is nigh, and the Prince of Darkness has been given one last shot at redemption, if he can manage to live out a reasonably blameless life on earth. As a trial run, he negotiates a month of "trying without buying" in the body of struggling writer Declan Gunn. ("Incarnation, the angelic drug of choice. Unlike cocaine, not to be sniffed at.") Luce seizes the opportunity to binge on earthly delights, to straighten the biblical record (Adam, it's hinted, was a misguided variation on the Eve design), to celebrate his favorite achievements (Elton John, for one), and to try to get his screenplay sold, but the experience of walking among us isn't what His Majesty expected: instead of teaching us what it's like to be him, Lucifer finds himself understanding what it's like to be human.
Jag ser ingen referens till snö i helvetet, men kanske du tänker på den här avsnittet i kapitel 26:
I never really wanted this job. (As all dictators whine.) Trouble was, when we found ourselves in Hell everyone looked at me. (How to describe Hell? Disembowelled landscape busy with suffering, incessant heat, permanent scarlet twilight, a swirling snowfall of ash, the stink of pain and the din of . . . If only. Hell is two things: the absence of God and the presence of time. Infinite variations on that theme. Doesn’t sound so bad, does it? Well, trust me.)
