While watching the Olympics (I admit it, I am an Olympics junkie
) I caught the trailers for a new NBC series - Revolution. It appears to be largely based on "The Hunger Games" concept, (Heroine is a teenaged girl who is proficient with the bow and arrow), but reminded me to a couple of sci-fi stories; one I read long ago - Fredric Brown's "The Waveries"; the other S. M. Stirlig's "Dies the Fire" and its sequels. Both stories involve the sudden loss of electricity (and in Stirling's books, almost all modern technology, even gunpowder won't explode any longer). If you like dystopian sci-fi, you might enjoy this one.
However, the cynic and critic in me remember's Fox's "Terra Nova" which started okay, but soon degenerated into predictability.
