Finn is a hot night surfer, Thana a cool sun worshipper. They clash but click. Together, they dig into his past to find out why he was made eternal. Something wants him dead, all evolutionaries dead. An ancient scroll has the answer. What it reveals is as fantastic as it is devastating to both. Staying young forever has its perks. It can also lead to unending loneliness. Finn Nilsson has accepted that reality. After he stopped aging nearly a century ago, he also lost the ability to exist in sunlight. Riding waves by night is his one true joy . . . until he meets a young woman who challenges his tendency to self-isolate. Thana is Finn's polar opposite. Visits by Fu-mes offer futuristic versions of herself, life's possibilities. The most tempting is Finn. When he returns to the place of his immortal re-birth in Hawaii, she impulsively follows. Underwater visions seem hallucinatory until they start to manifest. Once the two connect the dots of his past with her future, they learn the truth: They are magnetically linked but not in the way either could have ever predicted.
