Clary and the Shadowhunters struggle to piece together their shattered world after a betrayal by one of their own leaves them reeling.

The Mortal War is over and sixteen-year-old Clary Fray is back home in New York excited about all the possibilities before her. She's training to become a Shadowhunter and - most importantly of all - she can finally call Jace her boyfriend. But nothing comes without a price.

This is a new urban fantasy full of vampires, werewolves and shape-shifters from the bestselling author of "The Mortal Instruments" series. It's London, 1878: sixteen-year-old Tessa Gray's priority should be finding her brother, not falling in love, especially with two boys.

If the only way to save the world was to destroy what you loved most, would you do it? The clock is ticking. Everyone must choose.
