The idea of the end of civilization might be the same in both books, but I felt Swan Song had more 'heart' to it than the Stand. There are similarities for both books, but each author has their own writing style and storytelling ways. Try not to look for comparisons and just read for the enjoyment. I'm glad you're liking McCammon!
Thank you I will continue on..it was just the idea of two opposing forces after the apocolypse,with supernatural overtones..the character of the young boy akin to the trashcan man,being the stooge of the military guy and the guy who was a lot like randall flagg..other things too I noticed as I read through,not trying to be overly critical but just my op,as we all everyone has one! will keep reading tho,liked boys life and will check out others after finishing speaks..
