City of Lost Souls

by Cassandra Clare

Spice 2 out of 5, Simmer2/5 · Simmer: Closed door

What price is too high to pay, even for love? When Jace and Clary meet again, Clary is horrified to discover that the demon Lilith's magic has bound her beloved Jace together with her evil brother Sebastian, and that Jace has become a servant of evil. The Clave is out to destroy Sebastian, but there is no way to harm one boy without destroying the other. As Alec, Magnus, Simon, and Isabelle wheedle and bargain with Seelies, demons, and the merciless Iron Sisters to try to save Jace, Clary plays a dangerous game of her own. The price of losing is not just her own life, but Jace's soul. She's willing to do anything for Jace, but can she still trust him? Or is he truly lost?
