" If she’d been quizzed as to His Grace’s eye color, she would’ve had to reply simply that they were dark. Which they were. Very dark, nearly black, but not quite. The Duke of Wakefield’s eyes were a deep, rich brown, like coffee newly brewed, like walnut wood oiled and polished, like seal fur shining in the light, and even though they were rather lovely to look at, they were as cold as iron in winter. One touch and her very soul might freeze. "

― Elizabeth Hoyt , Duke of Midnight (Maiden Lane, #6)
