Librarian Note: this is an alternate cover edition for ASIN: B00SZQ9WFK. When Gianna wakes up on a cloud, she is disoriented yet fascinated. She thinks she's only dreaming until she gets a storm of paper planes—"They're thoughts of people who remember," a man on another cloud tells her—each pleading for her not to leave. The man tells her these planes are the key to get out of there, and while she thinks it's hard to believe, she decides everything is worth trying if it meant finding her way back home.
