Kane Azeka wakes up inside the head of teenaged Dana Hallis, told to record Dana’s memories by a mysterious being. He and Dana have to survive, together, on the alien moon Nysus, where the wildlife thinks industrial materials are delicious, unprotected machines rot quickly in the lowland jungles, and the human colonists destroy scions like Kane whenever they find them.
