Writing a book is a little bit like going on an expedition. I am very grateful for my intrepid co-Expeditioners. Huge thanks to Esmond Harmsworth and everyone at Zachary Shuster Harmsworth, and to Andrew Leland, Brian McMullen, Sam Riley, Dan McKinley, Sarah Manguso, Bennet Wade Bergman, and everyone at McSweeney’s McMullens. Thanks to Katherine Roy for her friendship and her beautiful illustrations. I am overwhelmingly grateful to my early readers, who made this book better in many ways: Lisa Christie, Sarah Piel, Griffin McAlinden, Zoe McAlinden, Remy Lambert, Sam Seelig, and Jon Secrest. I am so grateful to Amanda Ann Palmer for her friendship and for taking such good care of my kids. And big, Mammoth Elephant-sized thanks to my family, Matt, Judson, Abe, and Cora Dunne, and Sue and David Taylor, for going on this adventure with me.
