The colour of magic was gold . . . Aurelia Schwartz has spent twenty-three years maintaining the equilibrium between her carefully curated human life and the magical one that she endures in secret. With a devoted best friend and a place at an elite college in Cambridge, she has everything one could possibly want neatly within her grasp. Except for the fact that her gift of green magic has begun to fade – and, if that isn’t enough to upset the balance of her life, a fateful run-in with another power-hungry witch with a penchant for stolen magic has threatened to bring it all to ruin. Cast into an unexpected alliance with her dreadfully arrogant classmate, Aurelia goes into hiding among a peculiar family of witches, where she discovers that the secret to their safety requires breaking rules she has followed all her life: Make no promises. Tell no one what you are. And never stay the night.
