I'm not really a fan of Klingons, their culture and such. I'm old-school enough that my preferred alienated-aliens are the vulcans; I much prefer the logical, unemotional folks trying to understand and acclimate to human ways to the over-emotional, violent, hostile jocks with a chip on their shoulders, but this book does a fine job of exploring a setting in which Klingons are the protagonists (and not Anglicized Klingons like Worf or B'elanna, either.) It succeeds in a rather difficult undertaking: making the characters sympathetic without downplaying the fact that they ARE Klingons, from a culture which I despise. Not an easy task, but one that DeCandido accomplishes quite well.
And it's even well-written in terms of technical merit, too.
