After Robbie disappears, Sierra uses the chalk to draw three eyes and puts spirits into them, instructing them to find Robbie. The eyes lead her into the forest. Sierra hears humming around her, a chorus of voices “in rising and falling harmonies that filled the night” (142). Sierra soon realizes that she can see easier in the dark and that she can jump and soar in the air until she’s ready to come down. The humming continues around her, and she notices several shadows running alongside her. Realizing that Robbie will be waiting for her, Sierra runs her chalk along the trees and gathers the strength of several spirits, turning them into green shards that follow her to the meadow where Robbie is waiting. Robbie sends a red tide Sierra’s way, but she hurdles past him. Sierra draws more eyes and sends them and the shards after Robbie. He gives up, impressed by how quickly she picked up the skill. Sierra isn’t quite sure what happened, but she wants to do it again.
