I've read King Javan's Year all the way through several times, and there's something about it that makes me keep reading once I've started, maybe the closure they mentioned. I get anxious and frantic, and seriously ADD until I finish it, but still I end up finishing it. The Bastard Prince ends on a ray of hope. Rhys Michael was naive, but how dense could he be to stay naive after the way his brother died? And the more immediate things that he saw at the end of that book? Seriously.
For closure, I also would be curious to read a book on 948, even knowing that Joram and a lot of others were going to die at the end. The how and the why of it all is what would draw me. He's the one who survived the persecutions, it would be interesting to see the conflict that finally kills him--as long as it isn't something anticlimatic like dying of plague or old age.
