" The twins were nineteen, soon to be twenty, but one could be excused for thinking they were younger than their actual age. Raised in an atmosphere largely devoid of authority, they had run free on a country estate with few diversions other than those they created for themselves. Their parents had spent much of their time in London society, leaving their daughters in the care of servants, governesses, and tutors. None of them had been able or willing to take a firm hand with them.
To be certain, Pandora and Cassandra were high-spirited but also affectionate, intelligent, and endearing. And they were as beautiful as a pair of pagan goddesses, both of them long-limbed and glowing with health. Pandora was perpetually disheveled and full of energy, her dark hair falling from its pins as if she'd just been running through the woods. Cassandra, the golden-haired twin, was more compliant and romantic in nature, more willing to abide by rules. "
