If Tomorrow Comes

Nancy Kress returns with the sequel to Tomorrow's Kin, part of an all-new hard SF trilogy based on a Nebula Award–winning novella

Ten years after the aliens left Earth, humanity has succeeded in building a ship, The Friendship, in which to follow them home to Kindred. Aboard are a crew of scientists and diplomats, plus a squad of Rangers to protect them. But when the Friendship arrives, they find nothing they expected. No interplanetary culture, no industrial base—and no cure for the spore disease that ravaged Earth.

Instead of the expected instantaneous jump between worlds, more than ten years have passed.

The scientists find themselves in a race against time to save humanity from a deadly virus while a clock of a different sort runs down on a military solution no less deadly to all.
