The Seeds of Time — Kay Kenyon

A PILOT'S LAST RUN A PLANET'S LAST HOPE

Clio Finn is a Dive pilot, one of the rare, talented professionals capable of guiding a ship into the time stream. But she is walking the razor's edge of burnout-- which no Dive pilot has ever escaped--relying on drugs to buy her more missions. The future of Earth may depend on those missions into the distant past, in search of viable plant species to revitalize a graying planet. For Clio knows just how high the stakes are: she and two colleagues have made a forbidden Dive to the future, just long enough to record a dying Earth's last transmissions.

Now she is returning with a payload from an impossibly lush paradise. There is nothing she won't do, no crime she won't commit, to plant the seeds of new life on Earth--seeds that could halt the planet's death spiral...or destroy an entire civilization.
