Dragonsdawn

With time running out and the colony's destruction imminent, geneticist Kitti Ping Yung and her granddaughter Wind Blossom set out to bio-engineer Pernese lifeforms that appear to instinctively react to the Thread – the dragonets that colonists have adopted as pets. In order to ensure the survival of the newly designed species, as well as reduce the possible threat they may have to the colonists by going rogue, they are created with an ability to bond with humans. By the end of the book, Sorka Hanrahan and Sean Connell and a few other young colonists become the first of the dragonriders.
