Samhain-published Canadian Sheryl Nantus, from whom we received an official superhero urban fantasy
freebie* last year, offers a short romance story which she says has appeared in a magazine, and some kind of poetry collection, if you're interested:
linkage for the lot
* I read this one and while it wasn't spectacular†, it was actually pretty decent with some nice moments, enough so that I went and picked up the sequels during Samhain's Cyber Monday/Xmas sales with the 50% off coupon.

Astro City (or even
Noble Causes, which is basically superheroes done as a soap opera drama), so my expectations were kind of low to begin with and I ended up being pleasantly surprised‡.
‡ Mind you, I remind you that my expectations were low to begin with, and this is only a mild-to-medium recommend as long as you like seeing superhero tropes played with in a not-too-cliché considering the standards of the genre way.
Also, aliens invading Toronto, IIRC (it's been a few months since I read it and the details kind of blur).
