Philip Jose Farmer wrote the first short story of this concept in 1972. This novel follows up on the first Dayworld novel. It is not as good. He hooks up with other daybreakers in the woods of New Jersey (somehow suburban sprawl hasn't made it to this overpopulated world, but then that's sort of the point of the plot, PLOT SPOILER AHEAD: the overpopulation is just a government hoax. The other is ANOTHER PLOT SPOILER AHEAD, is the government is holding back an elixir (actually a living entity, bacteria or something) that prolongs life by a factor of 7. So the `stoning' process is no longer needed; there's no overpopulation, and people can now live 7 times longer. It's not clear why the government is withholding this anti-aging element, but dayworld rebel's goal is to get it out to the people. If you've read this review this far, IMHO, this is just about all you need to know. To read the book, is just adding a lot of words to sift through for the same information. Unfortunately in this case, the joy is not in the ride in getting to the end of the book, or the series for that matter, but in getting to the end.
My recommendation if you've read this far, is that you now know all you need to know about Dayworld. Skip reading this novel, and if you have not already done so, progress to reading the authors Riverworld series, starting with To Your Scattered Bodies Go. It even won a Hugo award so you can't go too wrong there.
