The sisters' voices were almost identical, laughing mezzos tuned in childhood to the same pitch and timbre. To the ear, they were twins; to the eye, nothing alike. Emily was tall and slender with her hair cropped short. She wore a pinstriped suit, elegant slacks, tiny, expensive glasses. She was an MBA, not a programmer, and it showed. Magnified by her glasses, her hazel eyes were clever, guarded, and also extremely beautiful. Her features were delicate, her fingers long and tapered. She scarcely allowed her back to touch her chair, while Jess curled up with her legs tucked under her. Jess was small and whimsical. Her face and mouth were wider than Emily's, her cheeks rounder, her eyes greener and more generous. She had more of the sun and sea in her, more freckles, more gold in her brown hair. She would smile at anyone, and laugh and joke and sing. She wore jeans and sweaters from Mars Mercantile, and her hair... who knew when she'd cut it last?
