<p> Unrequited love is hard enough when you?re a normal teenage girl, but for Lily Sanderson, there?s no such thing as a simple crush. </p> <p> Lily has a secret, and it?s not her huge crush on gorgeous swimming god Brody Bennett, who makes her heart beat flipper-fast. Lily?s mermaid identity is a secret that can?t get out, since she?s not just any mermaid?she?s a Thalassinian princess. When she discovered three years ago that her mother was actually a human, Lily finally realized why she didn?t feel quite at home in Thalassinia, and she?s been going to Seaview High ever since. Living on land has its problems?like her obnoxious biker-boy neighbor, Quince Fletcher?but it has that one major perk: Brody. The problem is, mermaids aren?t really the casual dating type?when they bond, it?s for life. </p> <p> When Lily?s attempt to win Brody?s love leads to a tsunami-sized case of mistaken identity, she finds out, quick as a tailfin flick, that happily ever after never sails quite as smoothly as you planned. </p>
