I wasn't all that impressed by the first of this series, but by book three I'm a convert! Each one has been steadily better and this is the one where I crossed the line from, oh I'll read them if I happen to run into them to, Rosemary Kirstein goes on my list of authors to watch for.
I am really enjoying the way she gradually builds up your knowledge of the characters and the world in which they live, adding layer on top of layer, each layer altering by a little or a lot your understanding of what has gone before.
Her characterizations are getting so good too. I am loving the people. Just terrific stuff.
