We are grateful to the following people for contributing to the complex route of getting this novel into print: John Silbersack and Robert Gottlieb, our literary agents; Tom Doherty and Christopher Morgan at Tor Books; Jan Herbert and Rebecca Moesta, our wives who provide comprehensive guidance; Diane Jones for test reading and providing comments; Kim Herbert and Byron Merritt at Herbert Properties LLC, who are dedicated to maintaining the Frank Herbert legacy. And, of course, it’s important to acknowledge Frank Herbert and his wife, Beverly Herbert, whose contributions as far back as the 1950s led, ultimately, to this new novel in the magnificent Dune series.
