The Copper Gauntlet

2015

Callum Hunt’s summer break isn’t like other kids’. His closest companion is a Chaos-ridden wolf, Havoc. His father suspects him of being secretly evil. And, of course, most kids aren’t heading back to the magical world of the Magisterium in the fall. It’s not easy for Call . . . and it gets even harder after he checks out his basement and discovers that his dad might be trying to destroy both him and Havoc. Call escapes to the Magisterium—but things only intensify there. The Alkahest—a copper gauntlet capable of separating certain magicians from their magic—has been stolen. And in their search to discover the culprit, Call and his friends Aaron and Tamara awaken the attention of some very dangerous foes—and get closer to an even more dangerous truth.

The Bronze Key

2016

Magic can save you. Magic can kill you. Students at the Magisterium are supposed to be safe. Under the watchful eyes of the mages, they are taught to use magic to bring order to a chaotic world. But now the chaos is fighting back. Call, Tamara, and Aaron should be worrying about things like pop quizzes and magic contests. Instead, after the shocking death of one of their classmates, they must track down a sinister killer… and risk their own lives in the process. As Call, Tamara, and Aaron discover, magic can only be as good as the person who wields it. In evil hands, it has the capacity to do immeasurable harm, unless it is stopped in time. In this striking third book of Magisterium, bestselling authors Holly Black and Cassandra Clare present us with a school where anything, good or evil, can happen, and the only way to unlock the truth is to risk everything to find it.

Author · 123 books

Cassandra Clare was born to American parents in Tehran, Iran and spent much of her childhood travelling the world with her family, including one trek through the Himalayas as a toddler where she spent a month living in her father’s backpack. She lived in France, England and Switzerland before she was ten years old. Since her family moved around so much she found familiarity in books and went everywhere with a book under her arm. She spent her high school years in Los Angeles where she used to write stories to amuse her classmates, including an epic novel called “The Beautiful Cassandra” based on a Jane Austen short story of the same name (and which later inspired her current pen name). After college, Cassie lived in Los Angeles and New York where she worked at various entertainment magazines and even some rather suspect tabloids where she reported on Brad and Angelina’s world travels and Britney Spears’ wardrobe malfunctions. She started working on her YA novel, City of Bones, in 2004, inspired by the urban landscape of Manhattan, her favourite city. She turned to writing fantasy fiction full time in 2006 and hopes never to have to write about Paris Hilton again. Cassie’s first professional writing sale was a short story called “The Girl’s Guide to Defeating the Dark Lord” in a Baen anthology of humor fantasy. Cassie hates working at home alone because she always gets distracted by reality TV shows and the antics of her cats, so she usually sets out to write in local coffee shops and restaurants. She likes to work in the company of her friends, who see that she sticks to her deadlines. City of Bones was her first novel. Sword Catcher is her most recent novel.
