I haven't read
Dawn, but the two Octavia Butler books I have read,
Parable of the Sower and
Parable of the Talents were both really, really good. That said, I don't personally care about owning books in general, and many of my favorite reads are checked out from the library. The Gibson books and
The Dispossessed are the only ones on the whole list I've actually read, but those three were great. I've heard good things about the Piercy book and look forward to reading it sometime.
I'd be really into reading your reviews of this stuff as you read them all. If you don't want to post them here, you should do so on
This Board.
