12-year-old Callum Hunt has grown up knowing three rules. Never trust a magician. Never pass a test a magician gives you. Never let a magician take you to the Magisterium. But Call is about to break the rules, and his life is about to change in ways he can't imagine. From the bestselling authors of the MORTAL INSTRUMENTS series and the SPIDERWICK CHRONICLES comes a magical new adventure series.
The first in a series of books about the sister of Sherlock Holmes, which inspired the upcoming film of the same name, which stars Millie Bobby Brown. First published in 2006. Ages: 12+
