When Ciara arrives on Alcyone, the Taniwha initiate an audacious assault aimed at her capture. They have amassed a formidable invasion force but need Ciara's singular ability to navigate the wormhole. Narrowly evading capture, she returns to Earth, only to find herself the quarry of a secretive faction known as 'Ananke'. Accused of smuggling weapons of mass destruction into South Korea, she is confined within the stark walls of a police cell. While there, Ciara has a vision of Scottie on the precipice of death at Kealakekua Bay on the day of James Cook's demise. Through her visions of naval officer William Hartley, Ciara learns that Ananke agents are Taniwha with human hosts. Over the centuries, they have shifted from person to person, infiltrating governments and the world's most influential organisations. When a startling discovery forces Ciara to return to Alcyone, she faces the challenge of mastering time travel to retrieve a critical artefact. Can she elude the clutches of Ananke, save Scottie's life, and halt the Taniwha invasion?
