City of Bones is an urban fantasy young adult novel that blends paranormal romance with action-adventure elements. The book combines contemporary New York City settings with supernatural demon-hunting, incorporating vampires, werewolves, warlocks, and angelic mythology. Cassandra Clare creates a hidden magical world existing alongside mundane reality, featuring chosen-one narratives and coming-of-age themes typical of YA fiction. The story balances fantasy world-building with teenage romance and family drama.

Shadowhunters in City of Bones are half-angel, half-human warriors also called Nephilim who protect the mundane world from demonic chaos and destruction. These demon hunters possess supernatural abilities granted through angelic runes marked on their skin using a tool called a stele. Shadowhunters have enhanced strength, speed, and healing, plus the Sight—the ability to see demons and other supernatural beings invisible to ordinary humans. They're governed by the Clave and follow the Accords regulating relations with Downworlders like vampires and werewolves.

The main characters in City of Bones include Clary Fray, a 15-year-old girl discovering her Shadowhunter heritage and searching for her kidnapped mother Jocelyn. Jace Wayland is the charismatic, arrogant Shadowhunter who becomes Clary's love interest and reveals he's Valentine's son. Simon Lewis serves as Clary's loyal best friend who secretly loves her and gets transformed into a rat by vampires. Other key characters include Isabelle and Alec Lightwood, fellow teen Shadowhunters, and the villainous Valentine Morgenstern seeking the Mortal Cup.

The Mortal Cup in City of Bones is a powerful talisman that Valentine Morgenstern seeks to create an army of Shadowhunters and overthrow the Clave. Clary's mother Jocelyn stole this sacred object and hid it away to prevent Valentine from using it to purify the human race by eliminating all Downworlders. Through recovered memories, Clary discovers the Cup is magically concealed within one of her neighbor Madame Dorothea's tarot cards. The Cup represents immense power in Shadowhunter society and drives the central conflict throughout the novel.

City of Bones features a central romantic storyline between Clary Fray and Jace Wayland, marked by immediate attraction and growing emotional connection. Their relationship develops as they search for Clary's mother, culminating in a midnight greenhouse kiss on Clary's sixteenth birthday. However, their romance faces devastating complications when Valentine reveals Jace is his son, making them believe they're siblings. The book also includes unrequited love from Simon Lewis toward Clary and romantic tension between Simon and Isabelle Lightwood.

The major twist in City of Bones occurs when Valentine Morgenstern reveals that Jace Wayland is his son, making Jace and Clary biological siblings just as they're entering a romantic relationship. This shocking revelation devastates both characters who had developed strong feelings for each other throughout their quest to find Clary's mother. The twist is later resolved in subsequent books when Jocelyn reveals Jace isn't actually Clary's brother—her real sibling is Jonathan Morgenstern, who had been masquerading as Sebastian.

City of Bones ends with Hodge Starkweather betraying the Institute by delivering both the Mortal Cup and an unconscious Jace to Valentine in exchange for his freedom. At Renwick's ruins, Clary rescues her unconscious mother and confronts Valentine, who escapes through a portal with the Cup after revealing Jace is his son. Luke's werewolf pack attacks Valentine's followers while Clary processes the devastating sibling revelation. The book concludes with Jace refusing Valentine's invitation to return to Idris, though their believed familial connection prevents Clary and Jace from pursuing their romance.

City of Bones targets readers aged 14 and up, fitting squarely in the young adult category with its 15-year-old protagonist and coming-of-age themes. The book contains fantasy violence including demon battles and murders, romantic content with kissing scenes, and mature themes involving family dysfunction and betrayal. While not excessively graphic, parents should note the presence of supernatural danger, some scary imagery with demons, and complex romantic entanglements. The writing style and pacing suit confident teen readers comfortable with longer fantasy novels.
