"Asylum" by Kathy Orzech
A Gilded Age lifestyle goes wrong in Asylum, a dark suspense saga.
In 1899 while her father travels abroad, twelve-year-old Maggie Delito unwittingly witnesses a shocking scandal. The next morning, she's dragged her family's estate and locked in an asylum to ensure her silence. Beneath the noted asylum's polish of respectability, a wicked villainy hides in dank shadows--and Maggie fears she will be its next victim.
Seventy-five years later Laura Delito inherits more than assets when her prestigious family's mysterious past comes knocking--a strange old woman, cryptic messages, and a rare antique key that might unlock the truth. As she pursues clues from the Northeast to North Africa, she fails to see the danger looming close to home.
