The First Law states:
A robot may not injure a human being, or, through inaction, allow a human being to come to harm.
The Second Law states:
A robot must obey the orders given it by human beings except where such orders would conflict with the First Law.
The Third Law states:
A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.
To My Brother Chris,

My Sister Connie,
And Her Husband Jim.
I would like to thank all the people involved with this book, and with this trilogy. It has been a long and complicated undertaking. Now, at long last, it is complete.
These three books would have been absolutely impossible if not for the prodigious literary output of the late Isaac Asimov, and if not for the prodigious popularity of his work. He is and will be greatly missed, and we are all in his debt. It has been an honor and a privilege to explore the ideas and the worlds he created.
Thanks as well to the editors who have labored over Caliban, Inferno, and Utopia. David Harris, John Betancourt, Leigh Grossman, and Keith R. A. DeCandido all worked to improve these books—and all succeeded. Thanks also to Susan Allison, Ginjer Buchanan, and Laura Anne Oilman of Ace Books, to Peter Heck, and to Byron Preiss, for their labors on my behalf.
And, of course, thanks as well to Eleanore Maury Fox. I hadn’t even met her when I started work on this trilogy. Now she is my wife. This is the spot where authors usually talk about the love, affection, and patience of their long-suffering spouses, and Eleanore certainly deserves thanks on all those counts. But I also got something else: very hard-edged, straightforward, professional editorial advice. It helped a lot.
I now come to my sister Constance Witte, my brother Chris Allen, my brother-in-law Jim Witte, and my sister-in-law Edith Allen. This last book of the trilogy is dedicated to them, as the first one was dedicated to their children. (Except for one, and I’ll come to her in a minute.) Connie, Chris, Jim and Edie: thank you, for a list of things that would be longer than this book. Thanks as well to my parents, Tom and Scottie Allen, and to my mother-in-law Elizabeth Maury, to my father-in-law David Fox, and to my brother-in-law, Carl Fox. The family just keeps getting bigger, and consequently I just keep getting luckier.
Speaking of families getting bigger, the newest member of it hadn’t quite arrived when I dedicated Caliban to my nieces and nephews. She deserves to be on the list. In closing, therefore, I would like amend that dedication to include Anna Patrice Allen. Welcome aboard, Anna.
