The Shadowhunters of Los Angeles star in Lady Midnight, the first novel in Cassandra Clare's newest series, The Dark Artifices, a sequel to the internationally bestselling Mortal Instruments series. It's been five years since the events of City of Heavenly Fire that brought the Shadowhunters to the brink of oblivion. Emma Carstairs is no longer a child in mourning, but a young woman bent on discovering what killed her parents and avenging her losses. Together with her parabatai Julian Blackthorn, Emma must learn to trust her head and her heart as she investigates a demonic plot that stretches across Los Angeles, from the Sunset Strip to the enchanted sea that pounds the beaches of Santa Monica. If only her heart didn't lead her in treacherous directions. Making things even more complicated, Julian's brother Mark, who was captured by the faeries five years ago, has been returned.
