Mercy, in Black — Stephen Donald Huff

Born into a wealthy family, Mercy Worth will enjoy every privilege that unimaginable riches can provide, but she will never know love. Her hair and eyes as dark as a starless night sky, from her first day on the planet she is unnaturally watchful and observant. Her intelligence is alien and terrifying, universally unnerving to all except her legal guardian. A tall, brooding attorney, he will watch over her rise to power with both fear and covetous jealousy, as he becomes convinced she is the Biblical Satan.No baby was more beautiful than Mercy, in pink. No toddler was more darling than Mercy, in yellow. No bride more brilliant than Mercy, in white. And humankind has never known anything as terrible as Mercy, in black.
