This was definitely a fun read, and--kind of like The Time Traveler's Wife but, of course, very different--not just the usual old thing. Not that the usual old thing (meaning a good book) is bad, but a fresh take never hurts.
However, I have to express the most spoilery of spoilers (don't say I didn't warn you): if you've read the book, you know it ends with her birth (yet again). I found this EXHAUSTING. I was sure at some point she would "get it right", would somehow snap out of the cycle, but the idea that it just goes on ad infinitum--or ad nauseum--was too much to bear. Of course, Sam was right; any sort of resolution would probably be a disappointment. But that didn't stop me from wishing for one, if only for Ursula's sake. Oh, and am I the only one who found myself eagerly awaiting her escape out of certain of her lives--the more awful ones, of course--so that she could start fresh and have a better life the next time?
Overall, my impression was distinctly favorable. Despite my complaints about the ending, we are already slated to read A God In Ruins.
