The castle shook again. Books fell from shelves in the library where Caden had brought Aria after the terrible roaring sounds started. Dust rained down from the stone ceiling like gray snow.
"What's happening out there?" Aria pressed her hands against her ears. The monster sounds made her bones hurt.
"I don't know." Caden's ice-blue eyes looked worried. "But we need to hurry."
He pulled a thick, leather book from behind other books on the top shelf. The cover was so old it looked ready to fall apart. Strange symbols covered the front, glowing slightly silver in the dim light.
"My grandmother hid this before she died," Caden whispered. "She told me to find it if anything strange ever happened to our family."
"Why are you showing me?" Aria's heart hammered as another crash echoed through the castle walls.
