The Ghosts of Orozimbo — H.J. Ralles

Henry's mother has fallen in love with Orozimbo, a dilapidated eighty-year-old cottage that is nothing more than a pile of rubble! Or is it? When Henry's parents purchase the old Texas cotton plantation, they get a lot more than just the property. Ghosts are everywhere! They threaten Henry and his cousin, Emily, and the two are caught up in a web of unresolved problems from centuries past. The only way for Henry to find peace is to solve the mysteries of Orozimbo.
