To my personal assistant Susan Morehouse for her friendship, patience, and enormous diversity of skills, and for keeping so many wheels in motion seamlessly.
To my brother, composer Greg Brown, whose inventive fusion of ancient and modern in Missa Charles Darwin helped spark the earliest notions for this novel.
And finally, I would like to express my gratitude, love, and respect to my parents—Connie and Dick Brown—for teaching me always to be curious and to ask the difficult questions.
