Yesterday's Kin Trilogy
3 primary works Complete
Book 1
Follows the arrival of alien embassies who meet with the United Nations amid human fear and speculation before obscure scientist Dr. Marianne Jenner is secretly invited to visit the aliens and prevent an imminent disaster.
Book 2
Ten years after the Aliens left Earth, humanity succeeds in building a ship, Friendship, to follow them home to Kindred. Aboard are a crew of scientists, diplomats, and 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. A timeslip in the apparently instantaneous travel between worlds has occurred and far more than ten years have passed. Once again scientists find themselves in a race against time to save humanity and their kind from a deadly virus while a clock of a different sort runs down on a military solution no less deadly to all. Amid devastation and plague come stories of heroism and sacrifice and of genetic destiny and free choice, with its implicit promise of conscious change.
Book 3
"The diplomatic mission from Earth to World ended in disaster, as the Earth's scientists discovered that the Worlders were not the scientifically advanced culture they believed. Though they brought a limited quantity of the vaccine against the deadly spore cloud, there was no way to make enough to vaccinate more than a few dozen, and the Earth scientists and surviving diplomats fled back to Earth. Once home, after the twenty-eight-year gap caused by their transit through space, they find an Earth changed almost beyond recognition. In the aftermath of the spore cloud plague, the human race has been reduced to a few million isolated survivors. The knowledge brought back by Marianne Jenner and her staff may not be enough to turn the tide of ongoing biological warfare" --
