Many thanks to all those who shared with me their time, expertise, and insight—particularly Doug and Kris Tompkins, Tom Butler, Kassie Siegel, Brendan Cummings, Kieran Suckling, Peter Galvin, Roxanne Quimby, Jym St. Pierre, Andy Frank, Terry Tamminen, Carole Allen, and Peter Bahouth. Telling the eco barons’ story has been a rare and eye-opening privilege.
I could not imagine completing this book without the support and guidance of my editor, Emily Takoudes; and my agent and dear friend, Susan Ginsburg. And I can’t imagine completing anything without my partner, Donna Wares, and our Gaby and Eben.
I did have to finish without the help of my constant companion, Nikolai, our borzoi, who sat by my side daily through the last five and a half books. I miss him every day.
