I have to admit, as much as I'm looking forward to this new DTI, I'd love for Christopher to get back to Titan. Orion's Hounds might be the best Titan novel so far.
Or perhaps a standalone novel, like The Buried Age.
Christopher, if you had carte blanche right now, what novel would you love to write??
I second the call for Christopher to return to Titan. Martin's just not doing it for me. The Gum Nebula was turning out to be a fascinating place and I really want to get back out there and do some exploring. You know, new worlds and all that.
