I have not read every Klingon themed book available, but of those that I have none have centered exclusively around Klingons, warriors or otherwise.
Your success in finding what you seek, or at least something close to it, will also depend on how you define "warrior". This matter has come up in multiple threads; I suggest you scan the boards, find posts whose authors' beliefs resonate with your owm, and PM them to ask for their recommendations. Most will happily share with you the titles of their favorites. It is a rare Klingon indeed who does not enjoy sharing their views with others, frequently at top volume and/or knifepoint. I recommend you begin with the
Klingon Religion and Beliefs section and work your way out to any topics that interest you.
Another method of finding agreeable reading material is to follow the works of authors whose non-Klingon books you have found to be agreeable. If a given writer's presentation of Riker and Picard appeals to you, chances are that much of the rest of their model of the Trekiverse -- including Klindom -- will as well.
Both methods are far from foolproof. Allies do not necessarily agree on anything further than the issue that united them in the first place. Authors can be inconsistant from one book to the next, and there is an increasing tendancy within the industry to hand authors committee-written outlines to work from. (I have this on good authority from a Simon and Schuster rep.)
In addition, seeking the opinions of those with whom you already agree is limiting at best, and blinds one to a universe of other possibilities. I agree wholeheartedly with zan Klythe in his recommendation of
The Final Reflection as it is is one of a handful of books that serves as a common blueprint for Klingon society. You would also do well to read anything you can find from the
Resources for Klingon Culture list.
Another frequently overlooked source of good Klingon reading material is fanfic. Many people hold their nose and invoke Sturgeon's Law when confronted with the term, but there is some excellent canon-observant fanfic out there featuring your favorites from the screen.
One author whose Klingon works I have been repeatedly directed to is
Christine Francis. If you are willing to pick through the gravel in your search for gold, I would also recommend you spend some time at the Usenet group alt.startrek.creative. If you do not have a newsreader client (the preferred method of accessing Usenet), you can access it through
Google Groups. Some browsers come packaged with a newsreader. Links to free downloadable newsreader clients for all the major platforms can be found
here.
I am perplexed by your seemingly unwarranted disdain toward laundry kuve. Perhaps as a child you reported for mealtimes in such a state of filth that it was easier for your caretakers to wash you and your clothing at the same time...?
