>Pournelle's solo effort "Lucifer's Hammer", about the lead up to and aftermath of a comet impact, is well worth a read.

I have Lucifer's Hammer on my desk right now and the cover says quite clearly: "LARRY NIVEN AND JERRY POURNELLE (Authors of the bestseller FOOTFALL)"

I am not aware of *ANY* good book Pournelle has written on his own.
