Blood Music

Blood Music by Greg Bear

(You may notice this is not the book we voted on! Young Miles is out of print and there were a handful of cheaper used copies but not enough for everyone and it wasn't available as an ebook or audiobook so I decided this would be a better option. If we really want to read it we can do so next month.)
