In search of a potion for her dying mother, Clary sneaks into the City of Glass and is immediately caught up in a life-and-death battle. As the children of the Moon (werewolves), Night (vampires), and Faerie gather for a war that will rend the heavens, Clary calls upon her untrained powers to control an angel who will save or destroy them all. Readers should be familiar with the first two installments in the Mortal Instruments series, but there is nevertheless plenty of romance, loss, honor, and betrayal to make the journey worthwhile. An experienced storyteller, Clare moves the plot quickly to a satisfying end.


To save her mother's life, Clary must travel to the City of Glass, the ancestral home of the Shadowhunters -- never mind that entering the city without permission is against the Law, and breaking the Law could mean death. To make things worse, she learns that Jace does not want her there, and Simon has been thrown in prison by the Shadowhunters, who are deeply suspicious of a vampire who can withstand sunlight.

As Clary uncovers more about her family's past, she finds an ally in mysterious Shadow-hunter Sebastian. With Valentine mustering the full force of his power to destroy all Shadow-hunters forever, their only chance to defeat him is to fight alongside their eternal enemies. But can Downworlders and Shadowhunters put aside their hatred to work together? While Jace realizes exactly how much he's willing to risk for Clary, can she harness her new found powers to help save the Glass City -- whatever the cost?
