I know of a fan-made series which I remember seeing advertised somewhere a year or two ago (Star Trek: Phoenix), and it got me thinking: is there any canon Star Trek material (I know - not the best term but you get what I mean) that is set after Nemesis?
I've seen this question already, so I know STO isn't counted as canon.
Note though that I would count a TV series, fan-made or not, if it covers the time period after Nemesis. There are no official works, so who's to say that's wrong (and often the fans have a better idea of what would actually happen than the official writers!)
