Ultimately, the only reason I was able to write this book—in fact, the only reason I am still alive to tell this story—is because of my wife Amy and our kids, Harper, Owen, and Nora (and our new baby, who is due any day now). Amy saw something in me that I had not been able to find in myself, and instead of running away from me she ran toward us. Her belief in me and in our love has been so inspiring but also so steadying; I can only wish that everyone involved in the common struggle finds this kind of closeness and partnership with someone so grounded and so hopeful.
