The Missing

There are some series' that I haven't seen any new work in for some time. For some of them I haven't seen the authors being active here either... One of my favorite series is the SPA universe. Yet I haven't seen any activity in the universe or from any of the authors who wrote in it for quite some time. There are a couple of other universes that are on hiatus here as well but right now I'm quite tired and can't think of the names...
Anyway, maybe other readers here could post the stories they're missing too.
Have a nice day!
