Polaris Rising

This is an excellent female power fantasy. The main character is rich and tough and smart but also vulnerable enough to just barely not be perfect. Her love interest is similar except he's not rich. If you like steamy love scenes along with your space opera, this is perfect for you. I will, however, note that it could just as easily be a fantasy story with faster-than-light travel replaced by spell-driven teleportation and it would work equally as well. Including the element of "high courts" and stuff like that. That was a bit of a turnoff, but the action was driving enough that I could forgive it.
