"Forward’s book is a knockout. In science fiction there is only a handful of books that stretch the mind–and this is one of them!"
–ARTHUR C. CLARKE
"Bob Forward writes in the tradition of Hal Clement’s Mission Gravity and carries it a giant step (how else?) forward."
"Dragon’s Egg is superb. I couldn’t have written it; it required too much real physics."
"This is one for the real science-fiction fan."
"Robert L. Forward tells a good story and asks a profound question. If we run into a race of creatures who live a hundred years while we live an hour, what can they say to us or we to them?"
–FREEMAN J. DYSON
Author of Disturbing the Universe
"Forward has impeccable scientific credentials, and . . . big, original, speculative ideas."
–The Washington Post
