What are you
desperate to read? I have been waiting forever for the third volume,
The Third God, of Ricardo Pinto's boldly original and woefully underexposed fantasy trilogy,
The Stone Dance Of The Chameleon (first one being
The Chosen, then
The Standing Dead). And it dropped through my letterbox today!!

Soooo looking forward to that!
The other one that springs to mind is another loooooong-awaited fantasy next-volume,
viz George R R Martin's
A Dance With Dragons. When the previous volume,
A Feast For Crows, came out, his afterword suggested that he had written most of the next one already - but that was like
four years ago, man! Come on, don't do a Jordan on us!
