Lady Midnight is the first novel in the The Dark Artifices series.
Glitz, glamours, and Shadowhunters abound in this heartrending opening to Cassandra Clare's Dark Artifices series, 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 LA, 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 as a bargaining chip. The faeries are desperate to find out who is murdering their kind and they need the Shadowhunters' help to do it. But time works differently in faerie, so Mark has barely aged and doesn't recognize his family. Can he ever truly return to them? Will the faeries really allow it?
In a kingdom by the sea...
In a secret world where half-angel warriors are sworn to fight demons, parabatai is a sacred word.
A parabatai is your partner in battle. A parabatai is your best friend. Parabatai can be everything to each other—but they can never fall in love.
Emma Carstairs is a Shadowhunter, one in a long line of Shadowhunters tasked with protecting the world from demons. With her parabatai Julian Blackthorn, she patrols the streets of an secret Los Angeles where vampires party on the Sunset Strip, and faeries teeter on the edge of open war with Shadowhunters. When the bodies of humans and faeries start turning up murdered in the same way Emma's parents were murdered years ago, an uneasy alliance is formed. This is Emma's chance for revenge — and Julian's chance to get back his half-faerie brother, Mark, who was kidnapped five years ago. All Emma, Mark and Julian have to do is solve the murders within two weeks... before the murderer targets them.
Their search takes Emma from sea caves full of sorcery to a dark lottery where death is dispensed. As she uncovers the past, she begins to peel away the secrets of the present: What has Julian been hiding from her all these years? Why does Shadowhunter law forbid parabatai to fall in love? Who really killed her parents—and can she bear to know the truth?
The magic and adventure of the Shadowhunter Chronicles have captured the imaginations of millions of readers across the globe. Fall in love with Emma and her friends in this pulse-pounding, heart-rending new volume sure to delight new readers and longtime fans.
