I finished The Last Dark some while ago. There was a great deal of to-ing and fro-ing, of running away and fighting. In the end, I think all the loose ends got resolved, and Donaldson probably managed to ensure that he never has to write another Thomas Covenant book again. I'm not sure that this, and the previous three books, are going to end up on my bookshelves - I doubt I will want to re-read them.
Then I moved on to Ancillary Justice. I was less enthused about it than I expected to be, based on the awards and so on. It has a lot of interesting ideas, and I think it's well-written, but it didn't have the 'spark' that would have grabbed me. Maybe it would have helped if I had read it in one go, rather than intermittent 15-minute doses on the bus to and from work.
I've now moved on to some non-fiction: Germania by Simon Winder. It's a history of Germany from the Roman Empire up to 1933. It's a complex subject, and I hope I will finish the book understanding it better. After that it will probably be the same author's Danubia, a history of the Habsburg empire in Europe.
