Allison Montgomery wasn't your average teenage girl. She liked punk rock bands and dressed in all black almost all the time. She already had a hard time fitting in at her school in Cleveland, Ohio, so she figured she would have an even harder time fitting in at her new school in Sydney, Australia. When she meets Luke Hemmings, the typical bad boy who could get any girl he wanted, her life will take a huge turn. But for better or worse?

18 year old Chrissy Morgan is moving away from her Hawaiian home to live with her friend, Miranda Devon in California while her brother is on a swimming trip around the Pacific. Why, you ask? Chrissy's and her brother are half merpeople, but she's never told a soul her secret before she left Hawaii. But on the plane ride over to see Miranda she meets a certain curly haired British boy that turns her world around as she meets the rest of his amazing (and famous) friends. This is the story of how a boyband changes the life of one special mermaid, but will she trust them enough to change theirs?
