Bound to the Last Dragon

Engineer Nora is pulled by auroras into a future dragon realm. Bearing late Queen Aeryn’s face, she awakens the Heartseed. Dragon King Darian first mistakes her for his lost mate, then loves her true self. They foil Regent Silas’s power grab with the Crown and defy a deadly prophecy. When Nora’s path home opens, Darian destroys the Crown, renounces his throne and immortality, and they build a fate-free cross-world life.
