Clanbook Karnstein is a very nice effort to add another bloodline to the (already much time ago overpopulated) Vampire background, besides an imaginative love letter to a very seminal work of vampire fiction.
All that brief text is based on providing plot ideas and narrative elements that could surprise even veteran players, being very close to the personal horror mood of 1st and 2nd editions of the game: fortunately, there isn't anything vampion-esque or munchkin in the elements that it proposes, or in the new fan-made-up Discipline presented (even one of whose higher levels is, in fact, a sinister and dramatic plot device).
On the bad side, I think that is unnecesary and incongruous at all that "reverse stereotypes" chart - why would all the Clans have to know a very small, familiar, inbred bloodline, and have an opinion about it? And something worse: layout leaves much to be desired and even in certain parts some text appears to be missing. But in fact, those are minor defects in a nice done and very unexpensive product, that merely could need some revision.
