Based on the list of Boston-based lit you gave me, I found a number of promising leads. Most of these I haven't heard of before, so I'm mostly guessing from the one-line descriptions that they'd be relevant. (Notes in parens from the site; notes in brackets mine)
Atwood, Margaret. A Handmaid's Tale (1986) [Yeah, it's Cambridge, but what a classic...]
Dubois, Brendan. Resurrection Day ("Boston after a nuclear war, but in a patrallel universe, set in the early 1970s")
Marano, Michael. Dawn Song (sci-fi, 1990, a Succubus arrives in Boston)
Stratton, Robin L. Raising the Pentagon: Three Ancient Socerers Caught in a Time Warp Find Themselves in 20th Century Boston: A New Age Adventure (1990) [Not really sure about this one, but.]
Arellano, Robert. Fast Eddie, King of the Bees (2001) (" near-future dystopia, a future Boston")
Mills, Christopher. "Kill Me in the Morning." (2001) (vampire fiction) 9 Mar. 2002
Popkes, Steven, Slow Lightning (1993) (space station orphan lives with aunt in Boston)
Robinson, Kim Stanley. "Glacier." In Robin Scott Wilson. Paragons: Twelve Master Science Fiction Writers Ply Their Craft. [Maybe sf, maybe not.]
Smith, David Alexander, ed. Future Boston (1994) ("a new novel created by an ongoing workshop by eight Boston-area writers, it's the 21st c. and the city is the only port of entry on Earth for interstellar commerce")
-----. In the Cube (1993) ("a science fiction detective yarn set in a future Boston literally crawling with wierd aliens.")
----- and Resa Nelson, "The Last Out." In 2041, ed. Jane Yolen
