Remembering Siri(1983)

Dan Simmons

A novella which appears nearly verbatim in Hyperion as "The Consul's Tale". A Hegemony spinship ferries construction workers to and from Maui-Covenant, where a new farcaster portal is being constructed in orbit. A member of the ship's crew falls in love with Siri, an inhabitant of Maui-Covenant, and upon each return to the planet finds her aging and maturing dramatically due to the time-debt associated with each flight.
