Science Fiction

In a future where Earth's atmosphere is toxic, underground cities survive on recycled air and rigid rules. When engineer Elena discovers a secret passage to the surface, she risks everything to see the real sky.

On a Martian colony, a water surveyor maps the buried ice that keeps ten thousand people alive. When her instruments find a cavity far older than the settlement, she learns what the terraforming project really moves, and what an honest line costs.

An inspector of the rolls is sent to a small city whose accounts come up nine hours short every year for forty years. To reconcile the gap he must find the error, and the arithmetic shows there is none; the south ward has been paying.
