Longer

This is why I read science fiction. -Daryl Gregory

In Longer, Michael Blumlein explores dauntingly epic topics-love, the expanse of the human lifespan, mortality-with a beautifully sharp story that glows with grace and good humor even as it forces us to confront deep, universal fears.

Gunjita and Cav are in orbit.

R&D scientists for pharmaceutical giant Gleem Galactic, they are wealthy enough to participate in rejuvenation: rebooting themselves from old age to jump their bodies back to their twenties. You get two chances. There can never be a third.

After Gunjita has juved for the second and final time and Cav has not, questions of life, death, morality, and test their relationship. Up among the stars, the research possibilities are infinite and first contact is possible, but their marriage may not survive the challenge.
