The Iron Trial is set to be the first joint novel from Cassie Clare and Holly Black.  David Leviathan, author of Boy Meets Boy, is set to edit the book at Scholastic.

From Scholastic:

“This project is the culmination of years of work and brainstorming with Holly,” said Cassandra Clare. “She’s someone I’ve always wanted to write with, and I can’t express how proud we are of the story we’ve created, or how excited we are to work with Scholastic and David. And we can’t wait for people to read it, of course!”

“We’re so excited to be working on this series with David Levithan and everyone at Scholastic,” added Holly Black. “From the moment it crossed his desk, he totally got it. He’s been the perfect reader for the books and we know he’s going to be the perfect editor too.”

In this exciting new series, 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.

The series has also been optioned by Constantin Films, the same company currently working on The Mortal Instruments series.

The first book isn’t due out until 2014, but the comparisons have already begun between this series and another boy wizard who started at Scholastic. So let’s put it out there: yes, Callum is 12 years old when the series begins and seems to age five years over the five books. After that, there is little to compare. Needless to say, no matter the comparisons the book will be amazing.
