Book excerpt: Raised by three strange sisters, Albia has never known the secrets of her parentage. But when Macbeth seeks out the weird sisters to foretell his fate, his life is entangled with his unknown daughter's. When Albia foresees the terrible future, she becomes determined to save Macbeth's rival-and the man she loves-from her murderous father. Klein's seamlessly drawn tale makes it seem impossible that Albia was not part of Shakespeare's original play.
