The Shadow Market is a meeting point for faeries, werewolves, warlocks and vampires. It's no place for Shadowhunters, but through two centuries a Silent Brother has visited. Brother Zachariah was once a Shadowhunter called Jem Cartairs, and his love, then and always, is the warlock Tessa Gray. Now he is searching for a relic from his past.

Valentine Morgenstern buys a soul and a young Jace Wayland finds safety. In the Market is hidden a lost heir and a beloved ghost. But no one cnan save you once you have traded away your heart. Not even Brother Zachariah.
