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.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. less

On Lily Sanderson’s eighteenth birthday she’ll become just a girl—still a mergirl, true, but signing the renunciation will ink Princess Waterlily of Thalassinia out of existence. That leaves plain old Lily living on land, dating the boy she loves, and trying to master this being-human thing once and for all. Now that Lily and Quince are together, mer bond or not, she’s almost content to give up her place in the royal succession of Thalassinia... moreOn Lily Sanderson’s eighteenth birthday she’ll become just a girl—still a mergirl, true, but signing the renunciation will ink Princess Waterlily of Thalassinia out of existence.

Now that Lily and Quince are together, mer bond or not, she’s almost content to give up her place in the royal succession of Thalassinia. But just when she thinks she has everything figured out, the waves start to get rough. Lily’s father sends a certain whirlpool-stirring cousin to stay with her on land. What did Doe do to get herself exiled from Thalassinia and stuck in terraped form, when everyone knows how much she hates humans? And why why why is she batting her eyelashes at Lily’s former crush, Brody? The seafoam on the raging surf comes when a merboy from Lily’s past shows up—Tellin asks Lily for something that clouds her view of the horizon. There’s a future with Quince on land, her loyalty to the kingdom in the sea, and Lily tossing on the waves in the middle. Will she find a way to reconcile her love, her duty, and her own dreams? less

When Lily Sanderson decided to remain Crown Princess Waterlily of the mermaid kingdom Thalassinia, she knew she couldn’t just coast along in the current. But since she’s spent the last couple of years on land—with gorgeous human Quince by her side—Lily’s not sure she has the fins to lead a kingdom. Even her maddeningly pretentious cousin Dosinia seems to know more about ruling than she does... moreWhen Lily Sanderson decided to remain Crown Princess Waterlily of the mermaid kingdom Thalassinia, she knew she couldn’t just coast along in the current. But since she’s spent the last couple of years on land—with gorgeous human Quince by her side—Lily’s not sure she has the fins to lead a kingdom. Even her maddeningly pretentious cousin Dosinia seems to know more about ruling than she does. But Lily has to dive in deep to keep her promise to Tellin, her mer bond in name only, whose kingdom is suffering in the changing ocean climate. Lily knows this is a seven seas–sized problem: from sea animals dying to oil spills and threats to humans. They’ll need to create some serious waves to make the mer community aware and get it to join together to make things right. Even if that means facing one of the iciest queens in the mer kingdoms. Just when Lily thinks her double life on land and sea can’t get any more complicated, an ancient mer law might separate Lily and Quince after all. It feels as if the pair is up against a solid tsunami wave! In this third installment in the series that began with Forgive My Fins and Fins Are Forever, Lily will have to find a way to balance safety and justice for the mer people as well as for the humans she loves. less
