Librarian's note: A limited star-chart dust-jacket edition was issued by Kestrel Press; this standard release includes updated ephemerides and a foldout of the Atlas Array.
By 2169, the night sky is crowded and the ground is hungry. The only time junior xenohistorian Mira Ellison feels awake is when she threads herself into the Starlattice, a photonic archive braided through the Atlas Array above New Dakar. Mira has spent years decoding the glyphs of the vanished Procyon Choir, puzzles cached in comet ice, asteroid chapels, and the gutted freighter Peregrine's Wake—puzzles obsessed with lost constellations, obsolete radio jingles, and relics nobody remembers. Legends whisper that whoever completes the Choir's sequence will inherit the Lumen Vault, a moon-scale engine that can rewrite migration lanes and tilt the balance of power across eleven systems.
When Mira stumbles upon the first harmonic at Helix Yard, she trips alarms that draw the Veil Cartel, Navy salvage teams under Commodore Rusk, and streamers who can turn a murder into a sponsorship. The chase erupts from the dunes outside Nouakchott to the hollow heart of Kepler-186f's captured shard, through blackout markets and lightless docks. To survive long enough to finish the sequence, Mira must outfly, out-think, and out-sing her rivals—and step beyond the lattices she trusts, into a scarred world that needs more than cleverness and stars.
