Over There is a pretty crazy novelette. Published in Asimov's the tale begins in a lab where a team of three conducts an experiment involving the wave function. From there, reality splits. And so does the story.
Never before have I read anything that changed from one column to two independent columns. It was incredibly disorienting at first. Several pages passed by before I realized that there wasn't a formatting error, one reality took place in one column, while the other resided in the second. Better yet, columns ended mid-sentence sometimes! Crazy. I'm not quite sure if it's crazy genius or just...crazy.
The writing was overall high quality. There were a few bits that could have been edited more, but it gets an 8/10 or so in that respect. I would have preferred it without the swearing, there wasn't too much point to it, yet that wasn't a deal-breaker. I'd give the writer's other work a go if I had the time.
I haven't read a whole lot of sci-fi, but Asimov's has opened up the genre a bit to me. What I've read of it so far, including Over There, has been satisfying.
