A few of the people who helped to make this book possible are: Dr. Joelle Murray, my only science-savvy friend, whose facts I keep messing with; Mÿk Olsen, my husband, who keeps me sane, for the most part; Michael and Denise Okuda, for the brilliant encyclopedia and chronology, which kept me from drowning; and Marco Palmieri, my editor, who deserves most of the credit for this novel’s outline, and a vacation.
