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.
