“The old gods may be great, but they are neither kind nor merciful. They are fickle, unsteady as moonlight on water, or shadows in a storm. If you insist on calling them, take heed: be careful what you ask for, be willing to pay the price. And no matter how desperate or dire, never pray to the gods that answer after dark.”
― V.E. Schwab, The Invisible Life of Addie LaRue
