What's the Story?

In CITY OF BONES, Clary goes to an all-ages nightclub and encounters Shadowhunters and demons -- both of whom are invisible to everyone else. This encounter, and her mother's subsequent kidnapping, brings Clary into a shadow world of age-old warfare between Shadowhunters and demons, vampires, and werewolves. Working alongside teen Shadowhunters Jace, Isabelle, and Alec, Clary discovers that her mother's past -- and, by association, Clary's own past -- aren't what she thought. In fact, she finds out she's intimately involved in a power struggle among Shadowhunters.

Is It Any Good?

Our review:
Parents say ( 31 ):
Kids say ( 220 ):

Teen urban fantasy is a popular subgenre, and this first installment of a six-book series has the essential elements. In City of Bones, author Cassandra Clare offers a complex world with reams of backstory involving many characters, creatures, factions, and relationships. In addition to the various sides among Shadowhunters, there are also vampires, werewolves, faeries, warlocks, and others, each with their own politics, powers, and agendas. Unfortunately, Clare's characterization of teen behavior (jealous girls, boys who evaluate girls' bodies and then get violent when upset) is clichéd. Paired with the lack of diverse characters and a reliance on racial, gender, and sexual stereotypes, the book feels outdated.
