Three seventh-grade students -- Nomi, Vi, and Arthur -- revisit a childhood discovery: a book of prophecies that once seemed reassuring in its predictions of the future. As they enter middle school, their friendship becomes strained by changing interests, personal secrets, and social pressures. When events described in the book begin to unfold alongside escalating wildfires threatening Seattle, the friends question whether the final prophecy foretells impending disaster. Confronting misunderstandings and fears, they must decide whether to rely on fate or on one another as they navigate uncertainty and the challenges of growing up.
