DeCandido delivers a great tale. The Deathless particularly appealed to me because he drew on a lot of Russian mythology, particularly the Baba Yaga tale. The Buffy characters were ‘true to life’ from the show, yet the story itself (AFAIK) was never an episode. This is the ultimate “YES” for tie-in work; you feel like you’ve just watched a particular fantastic episode without ever having to flip on the set.
Also there are reviews out there for Farscape: D'Argo's Trial #2 by Andrea Speed of comiXtreme and Louis Johnson of Fandomania.
