Probably the one that grabbed me the most was Made Things by Adrian Tchaikovsky. I read Children of Time years ago, but bounced off of Children of Ruin and hadn't read anything else by him. But reading Made Things on a whim this past year set me off on a Tchaikovsky binge that took up much of the rest of the year. I especially liked The Final Architecture books.
The book that I enjoyed the most just in and of itself though was probably Early Riser by Jasper Fforde. It's a fascinating concept, and more straightforwardly written than most of Fforde's books (I like his writing, but he has a regrettable tendency toward style over substance that was refreshingly absent from this one).
Mmm...
I thought that The Peripheral was the best book Gibson's written since at least Idoru, and I was very impressed and pleased.
But I think that Agency is quite possibly the worst book he's ever written.
