I read this a while ago, when I actually could finish a book, and I didn't take science fiction so seriously. It has kind of a weird ending SPOILER ALERT: LIFE GOES ON, the lesson seems to be that even though all petroleum and all plastics have disappeared overnight, you can still have an awesome rock 'n' roll concert at Altamont Pass, just like the good old days.
I like SciFi and if it is set in the SF Bay Area I'll tend to read it even more. This book is totally plausible. Just in 2007 the Costco Busan hit the Bay Bridge and well...plastic is still around but all the factors to make this book real are here today. So maybe it isn't so scifi after all...except the rail gun!
I don't read much sci-fi, but I LOVED this book! I never read a book twice and I have read it three times. I always thought it would be a great movie.
