The demon Vitrine?immortal, powerful, and capricious?loves the dazzling city of Azril. She has mothered, married, and maddened the city and its people for generations, and built it into a place of joy and desire, revelry and riot. And then the angels come, and the city falls. Vitrine is left with nothing but memories and a book containing the names of those she has lost?and an angel, now bound by her mad, grief-stricken curse to haunt the city he burned.
