I’m so grateful to my family for the inspiration and support they give me every day. Thank you, Juan, Rachel, Ricky, Alex, and Daniel! Thanks also to my parents, Joan and Bob Jack, and my siblings, Lisa and Gordy Jack. And a huge thanks to the whole extended Grau, Jack, and Smith clans—you all make my life so rich.

A very special thank-you to my editor, Erica Finkel, and my agent, Molly Ker Hawn, who make everything they touch better. Thanks to the talented Joe Sutphin for his gorgeous covers and interior art. Thanks to my early readers, Ashley Shouse and Gordon Jack. And thanks to all the fantastic people at Abrams who brought this book to life and continue to get it into the hands of readers everywhere: Chad W. Beckerman, Jessie Gang, Jason Wells, Jim Armstrong, Christine Ma, Zachary Greenwald, Elizabeth Peskin, Jess Brigman, Elisa Gonzalez, Mary Wowk, Susan Van Metre, and Michael Jacobs.
