Holly Black's 'Book of Night' spins a bewitching tale where shadows are more than mere absence of light; they are a commodity of power and a currency in a clandestine world. Charlie Hall, a deft thief and a seasoned con artist, finds herself tethered to this world of gloamists—sorcerers who wield control over shadows, using them to infiltrate, intimidate, and dominate. As Charlie grapples with the shady legacy of her past and the entanglements of her current life as a bartender, she is thrust back into the throes of the gloamist's world when a figure from her history resurfaces. With her sister hungering for magic, her boyfriend's ambiguous nature clouding the truth, and the perilous web of murder and deceit sprawling before her, Charlie's resolve is tested as she navigates through threats both familiar and fearsome. As her adversaries vie for a coveted secret that promises dominion over the shadow realm and beyond, Charlie must confront the phantoms of her past and the duality within to seize control of her destiny.
