ferrous heaven : Borrowed sky book two

Halcyon Station, Europa: four thousand people living over a fracturing reactor housing, and a safety officer who's filed fourteen reports into a silence she's starting to think is permanent. It's the exact shape of the catastrophe that killed a planet — except this time, someone's watching.

Captain Kessa Voss knows this pattern. She's flown through it once already. When the Compact traces Halcyon's negligence back to the same corporate playbook that broke Mars, she leaves the world she rebuilt — and the daughter she once carried across sixty million kilometers of grief — to find out whether a catastrophe can be stopped in time, instead of only survived after.

Back home, that daughter is done being protected. Naiya Osei is nineteen now, and when a hostile lawsuit tries to strip her settlement's hard-won protections the exact week her mother is gone, she discovers she doesn't need anyone's permission to fight for it herself.

And sixty million kilometers away, an old ally turned reluctant enemy — the very executive whose negligence nearly cost Halcyon everything — starts pulling on a thread that goes back further than anyone expected: a funding structure older than the Compact itself, patient enough to have been waiting since before the first colonist ever left Earth.

Borrowed Sky is Book Two of the Ferrous Heaven Trilogy — a story about what it costs to keep a promise a second time, and how deep the ledger really goes. For readers who want their hard SF with real institutional stakes, morally complicated antagonists, and a found family still fighting for each other, one crisis at a time.
