Marrow Bay, a drowning harbour city, 04:10. Ada Calder works nights at the Evermore Vault, where forty thousand uploaded minds live on in a paradise called Halcyon, to stay close to her father Elias, who died six months ago and woke in a reef that never bleaches. Tonight a data-destruction truck waits at the loading dock: at six, his hall and its 3,112 residents will be wiped to save power. A night-shift thriller of swallowed grief and dry wit.
