A little addition to "The Proposal"
I think this gives a clearer idea of why Sara's so reluctant to marry Pen:
They slept for a while, curled around each other, Penemuel still fatigued from his errand. Sara awoke in the middle of the night and watched his sleeping face – perfect, flawless, like living marble – in the dim light of her room. He appeared to be in his twenties, but in truth he was so ancient. The weight of his years, of his long and vast experience, made Sara feel insignificant. She shivered, almost fearful of the angel in her arms. Penemuel stirred, tightened his embrace, and smiled in his sleep.
Outside, the streetlights caught the raindrops hanging from the last autumn leaves, turning each one into a star, and together they made a shimmering, wind-blown galaxy that quaked in the trees. By morning, the stars had all fallen.
