I didn't see any thread about Supernormal Step, so I thought I'd start one.
Series Overview for New Readers:
Supernormal Step follows protagonist Fiona Dae, who is pulled by a strange portal from her home in Grand Rapids, Michigan into an alternate world with abundant magic. Part One (chapters 1-14) follow Fiona as she explores the magic world, gets drawn in to a series of conflicts between a range of factions with strange or unclear motives, and ultimately tries to find a way back to her home world. Part Two begins with Fiona and three of her companions from the magic world arriving back in the "real" world...only to discover it is not as Fiona remembers it.
Current Stuff:
Spoiler: Chapter 19So in the most recent chapter, we got a bunch of background about the origin of the magic world. We also finally got a confirmation as to how Cavan was originally pulled into the magic world (though the answer was a perfectly plausible guess before).
