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.

She mourns her dead and rages against the angel she longs to destroy. Made to be each other’s devastation, angel and demon are destined for eternal battle. Instead, they find themselves locked in a devouring fascination that will change them both forever.

Together, they unearth the past of the lost city and begin to shape its future. But when war threatens Azril and everything they have built, Vitrine and her angel must decide whether they will let the city fall again.
