<em>Replacement</em>, his only novel, published two years before Ulven's suicide, is a miniature symphony, wherein the perspectives of fifteen unrelated characters are united into what seems a single narrative voice: each personality, having reached a point of stasis in their lives, directing the book in turn. These people reminisce, dream, reflect, observe, and talk to themselves; each stuck in their respective traps, each fantasizing about how their lives might have turned out differently. A masterpiece of compression and confession, <em>Replacement</em> dramatizes the tension between the concrete realities we think we cannot alter, and our interior lives, where we feel anything might still be possible.
