V.e. Schwab said this quote

She sank her teeth into his bottom lip, drawing blood, and gave a wicked laugh, and still he kissed her. Not out of desperation or hope or for luck, but simply because he wanted to. Saints, he wanted to. He kissed her until the cold night fell away and his whole body sang with heat. He kissed her until the fire burned up the panic and the anger and the weight in his chest, until he could breathe again, and until they were both breathless.
