Christopher Golden has written several novels about the character, the first two of which, The Lost Army and The Bones of Giants, are part of the official Hellboy story canon. The events of both these novels are listed in the comic's official timeline featured in Hellboy: The Companion. In particular, the Golden-penned character of Anastasia Bransfield was also described in the companion, despite having never actually appeared in a comic.
