Look, don't get me wrong, I enjoyed Swan Song somewhat but just didn't think it was close to as good as The Stand and too much of a rip-off of it. All writers today rip-off old ideas but just not to the extent that McCammon did in Swan Song. Boy's Life was good too but not as good as Summer of Night, IMO. I hope me saying this won't keep you from reading those Simmons books, it's just my opinion and I can't expect anyone to agree with me.
Won't stop me mate, Carrion Comfort might even be my next read.
