Here is a fanfic based on John McCray's web novel "Worm". The newcomer, or rather a transmigrated soul from our world to the world of Earth Bat, is familiar with the canon up to and including the description of Slaughterhouse Nine’s visit to Brockton Bay. Warnings: hit and miss, new character, careful attitude to the canon (to the characters and spirit, and not to the letter, although if possible), total MC, the narration is conducted both on behalf of the main character and from the side of minor characters. To understand the text, familiarity with the canon, at least superficially, is very desirable. Well, naturally: cruelty, violence, 18+, etc. Read at your own peril and risk.
