Longer by Michael Blumlein

A tough, chewy look at longing, limits, and love. When a medical development allows for extended, though limited, lifespans, the struggles for discovering, and even preserving, what is now normal in human relationships play out on a very small stage. In a lab. On a space station. Staffed by a highly competent married couple in the employ of a powerful company. Michael Blumlein has crafted a gem of a story which shows more than it pretends to, placing the reader in the hearts and minds of the characters, and chooses none of the answers it offers.
