The Mortal Instruments Companion, a must-read guide to the wildly popular Mortal Instruments series, is a terrific gift for the millions of fans both young and old—especially with the Sony Pictures film version of City of Bones, the first book in the series, hitting theaters in August 2013.

Written by the New York Times bestselling author of The Twilight Companion and The Hunger Games Companion, the book takes fans deeper into the world of the Shadowhunters created by Cassandra Clare—a gritty urban fantasy world full of demon hunters into which Clary Fray, a Brooklynite previously unaware of the magical world, is suddenly and inexplicably pulled.

The Mortal Instruments Companion includes fascinating background facts about the action in all seven books, a revealing biography of the author, and amazing insights into the series’ major themes and features—from the nature of evil and the Downworlders, to the power of the Sight, to the Mortal Instruments themselves. It’s everything fans have been hungering for since the very first book! This book is not authorized by Cassandra Clare, Margaret K. McElderry Books, or anyone involved in the City of Bones movie.
