Siobhan, the foster daughter of the clan leaders has spent a year training to become the future Tsahik and Aonung's future mate. As the first human tsakarem, Siobhan has a lot of pressure on herself to be the perfect tsakarem in everyone's eyes especially after Ronal had chosen her as her successor. When the Sully family arrive onto her clan's shoreline, Siobhan begins a rivalry with Lo'ak Sully, the youngest son of Jake and Neytiri Sully after finding out that he has a crush on her best friend, Tsireya. As time passes in-between the pair and they turn from being enemies into friends, Lo'ak and Siobhan begin to realise that they have certain feelings for each other. However, Siobhan must make an important decision, she must choose to either become the future Tsahik and mate with Aonung or mate with Lo'ak and lose her position as the tsakarem of the Metkayina clan. Can Lo'ak and Siobhan be together or will their differences within their species tear them apart from each other?
