Dark Horse has released this artwork (see the full image below), teasing only that it's "coming soon from Dark Horse Comics and Caitlín R. Kiernan!" Fans of the fantasy author will likely identify the crouching figure as Dancy Flammarion, the monster-hunting albino from the Florida backwoods introduced in the 2001 novel Threshold. The character's adventures were later chronicled in the 2006 short-story collection Alabaster, which sports a cover and interior illustrations by Courtney Crumrin creator Ted Naifeh.
On her Livejournal, an excited but relatively tight-lipped Kiernan reveals the official announcement is coming Wednesday.
The author is, of course, no stranger to comics, having written The Sandman spinoff The Dreaming (for which she won Bram Stoker and International Horror Guild awards), and the miniseries The Girl Who Would Be Death and The Sandman Presents: Bast.
