H2O: Continued.

Book: "H2O: Continued."This story takes place after the "last" episode of "H2O: Just Add Water." I DO NOT own any of the original characters from H2O. Just a girl writing about her fav characters with a few new ones.This will be a confusing book for you (at the beginning) if you have never seen the show. I hope you watch it though, it's good!Decided to write this because I felt like 3 seasons was way too short for one of the best and most original tv shows in history.I am not from Australia, so, most of the things in this book according to money or language (or even dates) will not be super accurate.Notice: This is the precursor to the events that will be happen to the sequel of this book - Wisher: A Mermaid Tail.Anyways, I hope you enjoy reading it as much as I enjoyed writing it! [Started: Sometime in May 2019. Finished: January 26, 2020 (8:58pm😭)].My face rn ---> 😀
