The Copper Gauntlet by Holly Black

Holly Blackand Cassandra Clare first met over ten years ago at Holly’s first-ever book signing. They have since become good friends, bonding over (among other things) their shared love of fantasy — from the sweeping vistas of The Lord of the Rings to the gritty tales of Batman in Gotham City to the classic sword-and-sorcery epics to Star Wars. With Magisterium, they decided to team up to write their own story about heroes and villains, good and evil, and being chosen for greatness, whether you like it or not.

Holly is the bestselling author and co-creator of The Spiderwick Chronicles series and won a Newbery Honor for her novel Doll Bones. Cassie is the author of bestselling YA series, including The Mortal Instruments and The Infernal Devices. They both live in Western Massachusetts, about ten minutes away from each other. This is the second book in Magisterium, following The Iron Trial.
