Dawn

I found a recommendation for this book on a list of horror novels to read. I've always kind of been in awe of Butler, I remember reading Kindred in a stunned sort of trance-like manner. She's was a literary goddess, truly. Dawn belongs on horror recommendation lists. The entire point of this novel is the very frightening idea that, if there was no other choice, how much humanity could humans give up and still be human?
But, that's not the scary part. Oh, no.
For me, I found the isolation that Lilith endures to be awe inspiring terrifying. She is not only isolated in a room on a ship with a completely alien species, she is later forced into a leadership position of training fellow humans for a return to earth. But the humans are not going back alone or unaltered. I can't say more without giving away plot points, except poor, poor Lilith.
This is in every way a horrifying story of the future of humanity, and one I would never want to have to live through.
