One Moon Cycle by
TasiMom reviews
I had this idea floating around about how both shows are connected with a back story. The premise is that Rita lied when she said Harry died. Harry is Harrison Bennett. I hope you enjoy it. The story takes place shortly after the last season of Mako. Not all relationships are going to be the same. So, if you don't want changes, then this might not be the story for you.

This is a 'continued' story of H2O just add water. Characters from H2O and Mako Mermaids MAY appear in this story. Just read to find out :) Btw ik the title is cringy and stuff but I am cringy anyways so... Anyways hope you enjoy. Also, the chapters are pretty short, because I am used to writing short stories that are around 6 pages long. All I need to say, thanks! *In Progress*
