The Years of Long and Bored

About a week ago finished reading The Years of Salt and Rice.
It was a tough book to read, slow, and sometimes a total and complete boredom to carry on... But I've finally finished it.
The idea is quite good, but boy oh boy it takes Robinson quite a while to tell the story.
By far the best part is America's discovery by the Chinese, and when they come down here and slain the population.
For the moment not sure what to read next..
