El libro de la noche

He has spent half his life working for the Shadowers, people who can manipulate shadows to sneak into locked rooms, strangle someone in their sleep, or do even worse. The great zeal with which the Shadowers guard their secrets has created an underground market for grimoires. And to steal from their rivals... they need Charlie Hall. Although Charlie has been trying hard lately to get away from the mistakes of her past, it's not easy when you work as a waitress in a seedy dive, too close to the corrupt underworld of the Berkshires. Not to mention that her sister Ella Posey is desperate to become a Umbrist and Charlie's boyfriend Vince (who lacks a shadow and maybe even a soul) is keeping something from her. The return of a terrible figure from her past triggers a whirlwind of deaths and lies in which Charlie finds herself caught up. Determined to survive, she will have to deal with doppelgangers, capricious billionaires, Umbrists and even the people she loves most in the world; They all want to seize a secret capable of granting them immense and terrible power.
