This book has 3 big things going for it:
1. They're young adult postapocalyptic, which is rare.
2. All of the stories take place only *after* the disaster has occurred--it doesn't really matter how it happened (or even what happened).
3. There's a preponderance of female authors, for once.
As with all short-story collections, some of these are better than others. Standouts for me were the ones by Genevieve Valentine, Sarah Rees Brennan (long-time fan, here) and Cecil Castellucci.
