A dealer's room is a dangerous place

I know Stars in my Pockets ... is the first half of an unfinished duology; is it a sane second Delaney to read, after Triton long ago?

The first half of the Peter F Hamilton I have on (DRMed) disc, but the e-publisher hasn't released the second half in that format.

Several people pointed out even at the con that you can read award shortlists much more cheaply, in shoulder-strain and wallet-ache and waste of bookcase alike, if you wait a year ... but having obtained this pile, where should I start?
