I read in passing that Eleanor Arneson had a really good space opera series but wow is it hard to find her used books anywhere. I've checked all my haunts on the elite coastal cities I have the great fortune to visit and so far nothing. I got this one from a guy who was selling all his old paperbacks.
It's a fun read, but one of those disjointed sci-fi novels that seems to be testing out several concepts rather than really wanting to tell a story. It's about a young woman who lives on a colony planet, long since disconnected from earth. She is yanked from her college dorm to go to a remote colonial mansion where she is supposed to marry a high-bred native of the planet. Then it turns out the robot guardian is actually the original colonist and there is rocket ship in the mansion. Shit happens and they return to earth which is now a changed world, with uplifted (but kind of simple) rat communities in Manhattan and weirdly unmotivated humans in Brooklyn. And oh yeah the young woman has some kind of probability distortion effect so that extra weird things happen to her. The first half of the book, I kept wondering if some editor had just chosen that cover purely arbitrarily to sell the book but that scene does end up actually happening.
As you can see, it goes all over the place. Some of the places it goes are pretty interesting and cool, but you sort of wonder what it is all in aid of. I later read that this was her first novel, so I'm okay with that and will keep looking.
