1997 saw Rodent Press bring out a chapbook entitled prophets and brothers, a collection of four short stories by Brian Evenson. The cover is pretty basic though the word "prophets" does wraparound from the back to the front. There were 250 copies of this chapbook published. As a collection, it may be the most focused on Mormonism that he's put togehter--though I do wonder if that might not be aided greatly by the fact that there are only four stories and not 150 plus pages worth of work.
I looked online for this for a couple of years before I was able to track one down at a price I thought was reasonable.
Six years later, Earthling Publications put out a second chapbook--what at the time appeared to be a novella entitled The Brotherhood of Mutilation. This was put out in two versions, 300 signed and numbered softcovers copies (of which this is number 10) and 15 hardcover, lettered, traycased, editions (I've never seen a hint of a sign of one of these online over the last five or six years of looking).
Turns out that four years later, Evenson published another novella length work, "Last Days", in Unsaid Magazine. Close readers would notice that the protagonist in this new novella, Kline, is the same from The Brotherhood of Mutilation, and in fact, "Last Days" picks up where the other left off. Underland Press would publish the two works together as Last Days in 2009. It's a work that sticks with you long after you finish reading it. Typing this post has various scenes popping back into my head this evening.
