The Family Shame: The Zero Enigma, Book 4

Isabella Rubén is a traitor - at 12 years old.
Disgraced, abandoned by her friends and shunned by her family, Isabella is sent into exile with scant hope of returning to her former home. Her destination, Kirkhaven Hall; a stone mansion miles from civilization, inhabited only by a pair of older exiles. Existence as she knew it is over.
But as she tries to settle into Kirkhaven Hall and a life far from the one she enjoyed before her fall from grace, she discovers that the hall has secrets. Intruders on the grounds, ghostly shadows moving at night...and a plot that may destroy everything she once held dear.
