Wander

Allen was just minding his own business, trying to get by in the big scary world. But Narrators have a way of ruining stuff. Now, harried by delusions, a corporate band of Demons, and Oxygen itself; and with his only ally a Narrator who has too much time on his hands, not enough control over his story and a love of Mexican libations, Allen must find his way to some randomly determined spot in the desert. If he doesn't, the whole of existence might end. You should read it. I hear it's really good.
