Books like City of Lost Souls

City of Lost Souls is the fifth book in The Mortal Instruments series by Cassandra Clare. City of Lost Souls was released on May 8, 2012, and was followed by the sixth and final book in the series, City of Heavenly Fire in 2014.

The book opens with Simon returning home, where he finds out that there are a lot of symbols that form a barrier so he can't enter the house. He speaks to his mother, only to feel more rejected when she accuses him of killing the "real" Simon. Things become more tense when he learns from Clary that Jace is currently missing and untraceable. Clary and the rest of the group manages to gain the assistance of the Seelie Queen, but in return they have to obtain and hand over two Faerie rings that would allow the wearers to communicate telepathically. Desperate, Clary agrees to the terms and while searching for the rings in a Shadowhunter library, accidentally observes Jace enter the library and speak in friendly terms with Sebastian (Who is actually "Jonathan Morgenstern", Valentine's half-demon blooded son) - which confuses Clary, who had been hiding during the conversation.
