In Aotearoa New Zealand, Gabe explores cave formations and extraordinary wayfinding traditions connecting stars, currents, song, and memory. Mere is grounded, funny, and completely unwilling to let the triplets mistake fast listening for careful listening. A star-pattern Crossing leads toward a route-memory hidden in song, cave marks, and ceiling lights visible only under exact conditions. But disturbed evidence suggests the family may not be the first to arrive. Tala must recognize records that do not look like records, Rafi must distinguish damage from intent, and Gabe must admit that hidden knowledge can be collected as easily as it can be protected.
