Fifteen dragons embark on a dangerous journey into unknown lands in the hope of rediscovering ancient Kelsingra, the lost dragon haven. They are accompanied by human guardians who are also looking for their home. But is Kelsingra real, or is she just a piece of a glorious past kept deep in the dragons' memories? There are no reliable maps, and the dragons realize that in a land that has experienced so many natural disasters, their ancient memories are of little use. As they move deeper into unknown territory, people and dragons find themselves becoming something else. The stronger their friendship, the more severe the tests: greater hunger, more sudden floods, more dangerous predators. True, it soon becomes clear that the most dangerous predators are in the company of the travelers themselves...
