(Book 3) After a long journey of different, extraordinary worlds, the team return back in Arendelle. But in their present absence, evil was plotted. Jake has already taken control and Elsa doesn't seemed to notice. Her sister seems to be acting a little odd, too. No matter how much her friends-Rapunzel, Hiccup, Merida and Jack-try to convince her, Elsa refuses to listen. Is it because she chooses to ignore? Or, for some strange reason, she doesn't want to kick Jake Black out? Will Jack Frost win his Snow Queens trust back in time? Or will she make the wrong decision and be controlled by her own fear? Will all of them even make it?
