I can tell Feck is a smart and interesting guy, and he's cooked up a real nice ratatouille of random thought fragments here in Glabber. It's a good experiment, and I've definitely seen this type of thing executed much worse by other authors (stream of consciousness type stuff, that is). But when the author's goal is to give the reader as tenuous of a grasp as possible on what the writing speaks on, it can only go so far for me personally.
Side note: I picked up this book because the author, Mr. Speiderbeck, gained some attention on his local New Orleans Subreddit by posting kooky stuff related to this work. So good on him for hooking in some people to his self-published work that way.
