Ooh. I simultaneously so want to read this and don't want to. Cromwell is so rich, so engrossing, so brilliant and at the same time you could see him sliding into increasing flashes of hubris and sowing the seeds of his own death. But you also know he died in large part because the old-school aristocrats wouldn't tolerate his birth. Ohhhh.
I've read what Mantel said about the trilogy ending how it began and it's going to be a gut-punch.
