The plot arc of the novel, however, is decidedly less satisfying. About 2/3 of the way in, it seems, Mantel decides to make Thomas More into a counterfoil to Cromwell - he's been there all along, but suddenly he seems to be way, way more important. The ending is somewhat abrupt - the book is massively long, but it doesn't really have a plot arc, so there's no compelling reason why it should end at one moment instead of another. There are all kinds of people you know will turn out to be historically important, and are dying to spend more time with - this is where Mantel's skill in characterization sort of works against her - but you don't get to.
The big scandal around this book was that it won the Booker Prize over A.S. Byatt's Little Children. I haven't read the Byatt yet - it's on my shelf - but honestly, I don't think Wolf Hall is quite that spectacular. It's wonderful as a character study, but rather too long to be recommended solely on those grounds.
