The Drowned Hour

In Halloway Cove, a permanent fog swallowed the coastline the same night Wren Castellan's brother vanished into the strait — and now she's the last voice left broadcasting into it every midnight. When static on her graveyard shift starts forming words, then sentences, then secrets only the dead could know, Wren realizes the fog isn't empty: it's a waiting room, and every voice she lets speak through her airwaves has to trade places with someone still breathing.
