How far would you go for love? City of Lost Souls is the fifth volume in the bestselling series The Mortal Instruments by Cassandra Clare.
When Jace and Clary reunite, she is horrified to discover that the demon Lilith's magic has bound Jace to Sebastian. Clary's wicked brother has turned Jace into a servant of evil. The dual threat drives the Clave to destroy Sebastian at all costs... But there's no way to kill one without destroying the other.
To make matters worse, no one seems to believe there's a way to break the spell and free Jace. But Clary and her friends will try anyway. She's willing to do anything to save Jace. But can she still trust him? Will their love survive this new test? Or is all truly lost?
While Alec, Magnus, Isabelle, and Simon bargain with the Iron Sisters, higher-order demons, and the Fairy Queen in search of a solution, Clary decides to risk everything in a much more dangerous game.
But if Clary fails, she could lose her own life. And something she holds even more precious: Jace's soul...and the future of the Shadowhunters. New Marks, lies, and the memories of her Jace are her weapons.
Love, blood, betrayal and revenge... Darkness threatens the mortal world like never before in the fifth volume of The Mortal Instruments series.
