None of my books would be possible without the support of my husband Sean and the rest of my family. Thank you to my critique partner Denise Jaden, my muse for this series John Hughes, Greg Ng (and the moms from his class who volunteered to read a very early rough draft of this story), Rasadi Cortes, Erica Ediger, Jen Wilson, Belinda Wagner, Lisa Marks, Cory Cavazzi, my mom and dad, my brother Rob, my sister Luan, my editors Charlotte Ledger and Laura McCallen, and the entire team behind the scenes at HarperImpulse and HarperCollins Publishers. I’d also like to send a special thank-you to the real Search and Rescue volunteers and first responders in the Squamish area, and the young adult bloggers and youth librarians who tirelessly introduce books to young readers.
