Fins are Forever

Lily Sanderson has a secret, and it's not that she has a huge crush on
gorgeous swimming god Brody Bennett, who makes her heart beat
flipper-fast. Unrequited love is hard enough when you're a normal
teenage girl, but when you're half human, half mermaid, like Lily,
there's no such thing as a simple crush.
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 Lily found out three years
ago that her mother was actually a human, she finally realized why she
didn't feel quite at home in Thalassinia, and she's been living on land
and going to Seaview High School ever since, hoping to find where she
truly belongs. Sure, 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 -
the instant 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 is in for a tidal wave of relationship drama, and she finds out,
quick as a tailfin flick, that happily ever after never sails quite as
smoothly as you planned.
