The Tail of Audrey and Aryella

Audrey hasn't really ever had a perminate home. Moving from place to place shed gotten used to not getting used to places. Her father slowed her to join any club or after school program she wanted. Except swimming. He's afraid of water so no swimming for Audrey. Then why are we moving to the coast of Georgia?
Aryella is the rightful heir to the throne in her underwater kingdom. Her father has always been a mystery to her and she loves the moon and land.
Audrey and Aryella were separated at birth, knowing nothing of the reason why or even each other. But one day Audrey and her dad move to the coast and find the real reason they were separated.
They're half mermaid.
Join this set of twins adventures into the unknown underwater world in mine (and a friend's) first book. The tail of Audrey and Aryella.

I wrote this book with an old friend at school. She's actually Aryella and I wrote out the Audrey parts. We each edited each other.
Another friend did edit grammar after us. Don't want to mention names online but they helped a lot.
Also this was our first book that we actually finished so please don't judge (it wasn't, however, the first book I published). Though do feel free to give friendly advice.
