The author would like to thank the most fabulous Caitlyn Dlouhy and the most marvelous Ariel Colletti for being utterly fabulous and marvelous, and she wants to give a big tip of the hat to Lyn Streck, science teacher extraordinaire. Thanks to Kaitlin Severini, pretty much the best copy editor ever, and to Sonia Chaghatzbanian, the most marvelous book designer. Thank you to the fantastic Laura Ferguson for all of her fantastic work, and lots of love and gratitude to the usual gang of family and friends who keep the author centered and sane, which is no easy job.
