When I started this book five years ago, I had no clue the journey it would take me on, how huge the world would become—how much it would make my brain hurt—or how much I’d learn along the way. At times the journey to publication felt never ending, but as I sit here at the finish line, it feels like yesterday I was staring at a blank page one. I’m grateful for every early morning, late night, and stolen moment I got to spend with these characters and that wouldn’t have been possible without a massive support system. So, first and foremost, thank you to my husband Jason for always being up for an adventure (Spy School!) and for being the other half of this balancing act. I’m so happy we continue to grow together and dream BIG together. Thank you to my parents and to Joan and Joel for all the afternoons and nights at Grandma and Pap’s and Nana and Papa’s so that I can take a (much needed!) escape to my imaginary world.

Thank you forever and always to Jennifer Pooley for believing from the beginning and sending all the lightning bolts. To Diane Samandi for cheering me all the way—and for always bringing the deep talks. To Jeff and everyone at MGT for allowing me to make my own schedule so I can lead a double (triple?) life. To my editor Candace Havens for her incredible insight and for making me and KEYSTONE better. To everyone at Entangled—Liz and Heather and Curtis and Stacy and Debbie and Riki and Hannah and Jessica and Meredith and everyone I’ve yet to meet—who have had a hand in this beautiful book. I’m so happy to be a part of this team. To everyone at the Bent Agency for looking out for me. To Donovan, Lilah, and Cece for being my greatest joys in life. And finally, to you, the readers (if you’re still reading this!). Thank you for coming on this ride with me. You are the most important piece of the puzzle—the keystone, if you will—because without you this story would have no reason to exist. Thank you for giving me purpose. I’m forever in your debt.
