Acknowledgments.

Many thanks to all whose work, research, and support helped me to write this book, especially Dr. Howard Bluestein from the University of Oklahoma's School of Meteorology, who took time out of a stormy week in September 2010 to meet with me and answer my long list of questions, most of which began with the words, "So what if . . ." Dr. Bluestein also reviewed sections of this manuscript for scientific accuracy relating to the formation of tornadoes (even though the actual weather manipulation that happens in the book isn't possible at this time). His meteorological expertise is most appreciated, and any errors that remain are my responsibility alone.

I'm grateful to senior meteorology student Tim Marquis for the weather school and National Severe Storms Laboratory tour that provided much of the inspiration for the Eye on Tomorrow campus. The following books were also helpful: Tornado Alley: Monster Storms of the Great Plains by Howard B. Bluestein (Oxford University Press, 2006), The Tornado: Nature's Ultimate Windstorm by Thomas P. Grazulis (University of Oklahoma Press, 2003), and Storm Warning: The Story of a Killer Tornado by Nancy Mathis (Touchstone, 2008).

As someone who loves both science and art, I am fascinated by the idea of intersections between the two. Richard Holmes's The Age of Wonder: How the Romantic Generation Discovered the Beauty and Terror of Science (Pantheon, 2009) got me thinking about it in new ways.

I am grateful to poet Rita Dove for the gift of her work and for permission to include the excerpt from "Geometry" that Jaden reads in her faded paper book.

Thanks to student beta-reader Theo Gardner-Puschak for sharing his thoughts on the manuscript and to critique partners and writer friends Loree Griffin Burns, Eric Luper, Liza Martz, Ammi-Joan Paquette, Marjorie Light, Stephanie Gorin, and Linda Urban. You all make me a more thoughtful writer, and I'm grateful for your friendship.

Thanks to my agent, Jennifer Laughran, for supporting my writing, helping me weather storms, and generally being amazing; to my brilliant editor, Mary Kate Castellani, for asking just the right questions; and to Emily Easton, Beth Eller, Katie Fee, Kate Lied, Amanda Hong, Nicole Gastonguay, and the rest of the team at Walker/Bloomsbury, and to cover illustrator Vincent Chong.

A special thanks to Elizabeth Bluemle and Josie Leavitt of Flying Pig Bookstore, Marc and Sarah Galvin of The Bookstore Plus, and all the other independent booksellers who work hard for authors, books, kids, and communities every day. You rock.

Finally, thanks to Tom, Jake, and Ella. I saved you for last because the very best part of this book journey is sharing it with you.
