The Hitchhiker's Guide to the Galaxy by Douglas Adams
I've actually just read HHGTTG for the first time recently. Until a week or so ago I assumed it was a kid's story about a child that gets hold of some universal guide, and goes romping around the galaxy getting into zany alien-scapades. Apparently I was wrong! There aren't any kids to be found. But there are lots of other things, like death, improbability and manic-depressive super-genius robots. Lots of quirky humor and imagination. Missiles turning into whales, and the like.
I quite enjoyed it.
The aforementioned moribund robot's name is Marvin. He simply loathes humans. And, well, most of everything. Mostly because he is so much smarter than everyone. And everything. At one point in the story, he is assigned to stand around and watch over an entrance to a subterranean passageway. Then the main character, Arthur, calls him up a hill to join him, but changes his mind when Marvin is halfway up the rock face. Sighing in resignation, Marvin trudges back down the rocky hill and returns to his station.
Lots of head-hanging and dropped shoulders. And sleeping, haha.
About the Illustration
This booksketch was done using Micron Pen & watercolors. I had it in my head that Marvin kind of resembled Helper from The Venture Brothers cartoon, haha. One thing I took for sure from the book's description was that he had downward-facing red triangle eyes. And he was humanoid in appearance. And he was metal (of course).
