City of Bones

Cassandra Clare's City of Bones begins when Clary Fray sees a killing at a New York club that no one else appears able to witness. The teenagers involved call themselves Shadowhunters, warriors who hunt demons hidden inside the ordinary city. After Clary's mother Jocelyn disappears, Clary seeks answers from Jace and his companions; her friend Simon is drawn into the same concealed world.

The investigation overturns what Clary believes about her family and about the limits of perception. Runes, demons and Downworlders give the story its supernatural vocabulary, but secrecy is the more persistent force: adults have withheld information, institutions defend their own versions of order, and every new fact changes whom Clary can trust.

Read for the way urban fantasy makes belonging a problem of knowledge as well as ancestry. Clary's ability to see is useful, yet seeing does not automatically explain what she has found. Her choices test friendship, loyalty and the appeal of a ready-made identity. This overview establishes Jocelyn's disappearance and Clary's entry into the Shadowhunter world without revealing later family disclosures, betrayals or the final confrontation.
