I've just read Brinkmanship.
Quick impression? It's very strong, well-plotted and well-written, and morally ambiguous in a compelling way. (I'd argue that this book does for the Tzenkethi what The Romulan Way did for the Romulans. Interesting parallels between the two books.)
Wow, that was fast!
I can't wait to read your review. The Tzekethi version of The Romulan Way, huh?
