As per Goodreads:
Twelve-year-old Callum Hunt has grown up knowing three rules by heart. Never trust a magician. Never pass a test a magician gives you. And never let a magician take you to the Magisterium. Callum is about to break all the rules. And when he does, his life will change in ways he can’t possibly imagine.
Book One in the Magisterium Series – potentially a FIVE BOOK series.
The Magisterium series is a five-book series of fantasy novels, one book for each year of Call’s life between twelve and seventeen, cowritten with Holly Black (author of The Spiderwick Chronicles and the Modern Faerie Tale series) about Call Hunt and his adventures. The first book, The Iron Trial, will be published by Scholastic Books in 2014. Holly and I also have an option deal to produce the film along with Constantin Features.
Release date: October 2, 2014
My Reaction:
Two badass YA fantasy writers coming together to write something that sounds like Harry Potter fan fic?
(sorry about the wonky gif, just click on it)
Seriously, Holly, Cassandra… I will seduce a publisher for a signed ARC of this book.
