Maris Grainger and her dad have moved from Wichita, Kansas to Hawaii where she's been enjoying swimming in the Pacific and getting to know the other sea creatures. Because Maris isn't a normal girl, she's part siren. Which makes her as much a creature of salt water as the dolphins and seals who've become her best friends. But now it's time for school to start, and Maris doesn't know anyone at Kahalawai High School. Can she make friends while protecting her secret identity? She's about to find out!
