LEXI NIGHTS HAS A PROBLEM. Since the age of, well, since she can remember, she has been able to see and speak to ghosts. Her aunt, Arabella Figgs, says it natural, that it's normal. But, Lexi doesn't believe her, she means, who in their right sense of mind would?
DURING HER STAY AT HER AUNT'S, Lexi's letter to Hogwarts arrives and she's freaking out. She's a witch? She's means she always knew she was weird but witch weird? No. Oh, did she mention she speaks to ghost in Spanish? No? Oh, well now you know. Apparently, they understand Spanish (Lexi thinks they learned it in “the afterlife” or, maybe, they never spoke another language when they weren't spirits) and not English, which doesn't help if she's speaking to them at Hogwarts.
NOW, the Triwizard Tournament looming over Hogwarts, life only carries on getting harder, and a new ghost appears, one who speaks in English and get Lexi’s attention, because it was the first time in forever she hears a ghost speaking the same language as the originals Hogwarts ghosts.
