[Kaderin Triste]

It's been a while since I read Hitchhiker's guide, so I'm not sure how similar it is (definitely had some inspiration at least), but I suppose a case could be made that it's a more graphic/violent, mature, cruder, modern version of it maybe.

Just finished the second book and snorted so loud at the end when (not really a spoiler) Princess Donut points out to Carl that they're about to be whisked away for an interview and he's fully naked.
