The Honor Harrington stuff is great...other than being a billion books long. I don't mind a series, but after a while... Love O'Brien sea books, but 20+ books is a lot of dough and time for me.
As for casting her in a series? Claudia Christian.
"War is an ugly thing but not the ugliest of things; the decayed and degraded state of moral and patriotic feelings which thinks that nothing is worth war is much worse. A man who has nothing for which he is willing to fight, nothing which is more important than his own personal safety, is a miserable creature and has no chance of being free unless made and kept so by the exertions of better men than himself."
John Stuart Mill
