Alanna the Lioness has children :) Though most of the books about Alanna were some of Tamora Pierce's earliest, so the writing style isn't as sophisticated as it gets later, and also they are, like, young adult fiction. Not exactly high prose. The Will of the Empress (and in fact all the stories set in Emelan) also has female friendships, and Tris who really has no interest in romance at all and is quite happy to sit around talking to 70 year old men about crop production.
And she does interesting things with human limitations with Dove and Sarai in the Trickster books - Sarai is a really awful choice for a new queen, and it deals with that.
I'm a huge fan of Tamora Pierce, especially the Tortall books. The fact that her women can have careers and children and the fact that not every female character ends up paired to someone else are things that I really like about her writing. However, Tamora Pierce appears to be the exception to the rule. If you can prove me wrong, that would make me happy.
