A faerie heart is different from a human heart. Human hearts are elastic. They have room for all sorts of passions, and they can break and heal and love again and again. Faerie hearts are evolutionarily less sophisticated. They are small and hard, like tiny grains of sand. Our hearts are too small to love more than one person in a lifetime...I tried to talk sense into my hard little heart. But it had landed on Peter, a creature two hundred times my size and barely aware of me, and there was no prying it loose.
