The River Troll is strange and darkly comic illustrated Y/A novel
featuring a nameless protagonist we call "friend." Late at night our
friend wanders a little and ponders quite a lot on a long walk along a
river looking for a reason to keep on living. He meets up with a troll
and a few other all-night ghouls as he drifts along, searching for
purpose. They all find it amazing our friend can negotiate his way
through the day posing as a teacher.
