One of the earlier entries in the ongoing fascination we have as a culture with post-apocalyptic fiction. This one dates all the way back to 1993 with a strong young female character. (Literature has had room for a strong female lead long before the recent celebration of these kind of roles in film & TV. )
It wasn't a a page turner for me. But it was an interesting look at how a young woman forms a belief system and invites others into it, as a way of making meaning and hope when there isn't much to be found.
