The Almshouse (The Spirit World Series Book 1)

Come travel to the 1930's and through the doors of St. Margaret's School for Girls. The place used to be an almshouse, until its previous occupants burned to death thirteen years before. The townsfolk are at a loss as to what started the fire. Some said it was an act of the devil. Some said it was a resident who had too much to drink.
When a bag of bones falls on twelve-year old Julia, she finds herself thrown into the spirit realm with house's past residents. Her new neighbors aren't so lively, and some can't even remember their own names. But as Julia discovers, one of these ghosts is not like the others. Someone removed him from the town's history, and whoever did it would kill to cover their tracks.
