Sample · The Halcyon Key

Bay Enclave, 2043

The city didn’t sleep; it just entered a low-power state and dreamt of better days.

Max Mercer works the rain-soaked edges of Old San Francisco, where living intelligence grids run the towers and the sumps drown in ozone. When a scrambled voice offers twenty thousand credits to find Silas Vane’s missing chip, Mercer follows the Scarlet Lark into Aethelgard Dynamics, the Gilded Cage, and a weapon nobody should control.

A debt-ridden PI. A vanished inventor. A song that can unlock — or bury — the city’s darkest machine.
