Card is perhaps the most uneven author I’ve ever read.
Some of his stuff, such as Ender’s Game and Tales of Alvin Maker, is innovative and excellent.
Others, even some in the two series started by the books above, are almost unreadable.
His SF retelling of the story of the Book of Mormon, The Homecoming Saga, is atrocious.
I enjoyed Pastwatch: The Redemption of Christopher Columbus.
