Thersanom: The Hidden Secret

Abigail soon learns that her getting to Thersanom is a thing that should be impossible because the mermaids make sure humans and the non-magical creatures cannot get to Thersanom, and so she wishes to find out why she got there, and her memory loss is not very helpful.

Days after getting to Thersanom, Tarran's father had gone missing, and they quickly came to know that because of a secret he had been holding, the dangerous enfals of Isdar had taken him.

And so the group went on an adventure of finding Tarran's father and on the way Abigail learned a lot about Thersanom.
