paq'batlh: The Klingon Epic
It looks and feels like a cheap print on demand book. But it's the kind of thing that reminds me of what makes all of this fun.
paq'batlh: The Klingon Epic is a retelling of the classic tale of Kahless as an opera. You get English and Klingon text on facing pages. I'm no Klingon expert so I don't know if they got the story right or the Klingon text right, but Marc Okrand and other knowledgeable types were involved and there are footnote references to several TNG, DS9, and Voyager episodes as well as Michael Jan Friedman's Kahless novel, so I suspect they did their homework.
It's a fairly short work, telling in mythic style how Kahless became the legendary figure revered by the Klingons. I found it pretty enjoyable, and maybe the brevity helped. Anyway, anyone looking for something different in Treklit (and anyone who has the Klingon translations of Hamlet and Gilgamesh) should look into this. You can order this from the publisher or your local Amazon. If you're not sure yet, you can watch the video presentation at http://vimeo.com/32050802.
