Taylor Markham is now a senior at the Jellicoe School, and has been made leader of the boarders.
She is responsible for keeping the upper hand in the territory wars with the townies, and the cadets who camp on the edge of the school's property over summer. She has to keep her students safe and the territories enforced and to deal with Jonah Griggs—the leader of the cadets and someone she'd rather forget.
But what she needs to do, more than anything, is unravel the mystery of her past and find her mother—who abandoned her on the Jellicoe Road six years before.
The only connection to her past, Hannah, the woman who found her, has now disappeared, too, and the only clue Taylor has about Hannah and her mother's past is a partially written manuscript about a group of five kids from the Jellicoe School, twenty years ago.
