I think she is very of her time. Early stuff very influenced by first wave feminism and now she's very influenced by concerns about big pharma, big corps, dehumanising, lack of privacy and technology. Some very topical bits in this novel felt a bit shoe-horned in I thought but it's one of my few criticisms.
She's also got an arc of self reflection and introspection through to forecasting and analysing the external world. With the exception perhaps of the two slightly random historical novels that I didn't really think worked (too formulaic) even though they won loads of awards.
I love that she has range and variety. Haven't not loved anything I've read by her.
Will have to wait for paperback but I thought O&C and YotF could stand alone...also love that it's been a considerable time she's taken to write the whole trilogy, rather than bashing them all out in 18months
