Acknowledgments

We’d like to thank all our readers. There is nothing more exhilarating for an author than discovering people you don't even know have fallen in love with the characters and the story that you've worked so hard to bring to life. Thanks to every one of our friends and fellow authors who have read early drafts, or who have helped us understand the science we explore, or who have given us an encouraging word. With three co-authors, we each have particular people we'd like to thank.

From Amira—To the brilliant friends, talented authors, and wonderful people who answered questions my questions, gave us ideas, and supported me on this strange and wild journey, with particular thanks to Kristen Scheitler-Ring, Alexander Augustyn, Prashant Parmar, Lori Buchanan, Jason Finkes, Daryl Rothman, Jess West, Nillu Nasser Stelter, Jonathan Paul, and many more. A special shout-out to the fir trees of Oregon, the green rolling hills of California, and the sweet blue water of the west coast for keeping me grounded and inspired as we brought these books to life.

From Elena— I want to thank the sun, moon, and stars for always reminding me what's truly important. Much appreciation to friends who supported me on this sometimes arduous and many times enlightening journey of writing books. Special thanks to my sister and co-author Amira who pushed me through to the end and who daily inspires me with her passion and perseverance.

From Kristy—Thanks to my mom and my two sisters, to Jason for putting up with me, to my steadfast friends who believed in me, and to my amazing daughters for helping me bring Remy and Vale to life, and for going along with me on the most gratifying adventure in my life.
