Hilary Mantel's sequel to Wolf Hall, out soon, is called Bring Up the Bodies. It already has a very positive review in the New Yorker.
Mantel's prose is concise and beautifully written; Wolf Hall was one of those books that I didn't want to finish so I'm looking forward to reading this. She has not only made a very readable hisory novel, but also made Thomas Cromwell likeable in many ways. A rare feat many people would say.
